The twofold diabatization of the KRb (1 ∼ 2) We performed a diabatization of the mutually perturbed 1 1 Π and 2 1 Π states of KRb based on both electronic structure calculation and direct coupled-channel deperturbation analysis of experimental energies. The potential energy curves (PECs) of the diabatic states and their scalar coupling were constructed from the ab initio adiabatic PECs by analytically integrating the radial ψ ad 1 |∂/∂R|ψ ad 2 matrix element obtained by a finite-difference method. The diabatic potentials and electronic coupling function were refined by the least squares fitting of the rovibronic termvalues of the 1 1 Π ∼ 2 1 Π complex. The empirical PECs combined with the coupling function as well as the diabatized spin-orbit coupling and transition dipole matrix elements are useful for further deperturbation treatment of both singlet and triplet states manifold. I. INTRODUCTIONThe accurate representation of the interacting electronic states plays a key role in understanding the detailed mechanism of the photo and collisionally induced chemical reactions. The singlet-triplet levels of alkali metal dimers serve as an intermediate state in the two step optical transformation of the weakly bound atomic pairs into the absolute ground X 1 Σ + (v = 0, J = 0) molecular state 1,2 . To suppress the undesired spontaneous transitions to the low-lying states a coherent stimulated Raman adiabatic passage 3 (STIRAP) is often used.The photoassociative production and trapping of ultracold KRb molecules has been performed 4 . The resonance coupling of the B(1) 1 Π and 2 1 Π states of KRb (see, Fig. 1) is found to be a promising pathway for direct photoassociative formation of the X(0, 0) ultracold molecules 5 . The rigorous multi-channel modeling of the laser formation of vibrationally cold KRb molecules has been accomplished in Ref. 6 9,10 to the lowest X(0, 0) level through the B 1 Π ∼ c 3 Σ + levels located near the second dissociation threshold.A comprehensive review of modern spectroscopic studies of the KRb electronic states can be found in the ebook 12 . The mutually perturbed 1 1 Π and 2 1 Π states converging to the second K(4 2 S)+Rb(5 2 P) and third K(4 2 P)+Rb(5 2 S) dissociation thresholds were investigated 13,14 using Doppler-free optical-optical double resonance polarization spectroscopy (OODRPS). In the sub- 15,16 included in the present CC deperturbation analysis. The inset enlarges the region in the vicinity of the crossing point of V1(R) and V2(R) diabatic PECs.The adiabatic potentials, permanent and transition dipole moments for the radially coupled 1 1 Π and 2 1 Π states were first ab initio calculated in Refs 19 and 20. The comprehensive set of non-relativistic PECs, permanent and transition dipole moments for the ground and excited states of KRb are available 11,21-25 as well. The SOC effect has been included into ab initio calculations in Refs. 6,11,24,and 26. Among other alkali diatomics, the KRb molecule stands out because of the high density of the electronic states belonging to both...

Both fully relativistic and scalar-state based perturbation models provided the spin–orbit functions of the LiM (M = Na, K, Rb, Cs) molecules at almost experimental level of confidence.

The purpose of the research is to study the practice of its manifestation in the modern political process of Russia, in particular in Moscow, Yekaterinburg and Shies, based on the analysis of scientific ideas about political activism in social networks. The main methods in the work are the comparative political science approach, case-study and content analysis. The analysis of recent political events shows that modern online technologies and forms of civic participation are gaining great importance in political discourse. With the advent of the Internet, the approach to an audience in the media space and the forms of interaction have changed. There are spontaneous emergence of Internet activism in Russia and the growth of its influence which were described. The role of the Internet in activating citizenship was examined, the main channels / Internet platforms (YouTube, telegram channels, etc.) and their functions in Internet activism were highlighted. It is argued that online activism and subsequent offline actions were shaped by network structures as unique events open to any participant. A study of political protest actions in recent years shows that, at this stage of the developing civil society in Russia, Internet activism, which has consolidated various segments of the locals around solving political issues, contributes to civil mobilization and raises awareness of protests. In some cases, the agenda in the Russian media can be formed mainly due to the activation of the masses in the digital environment. It is concluded that in the short term because of the growing dissatisfaction with conventional forms of political participation, the confrontation between authorities and society in the Internet can create a new political reality in Russia. Protest actions organized using the Internet, previously not frequent, have become very common in Russian politics in recent years. The practical significance of the work lies in the area that the results of the study make a certain contribution to development of the theoretical base of researches on Internet activism.
