Time-resolved studies of photoinitiated reactions in binary and larger (N2O) m (HI) n (m? 1, n? 1) complexes

The H+N2O→OH(2ΠΩ,υ′,N′)+N2 reaction: OH rotational angular momentum polarization

“…The results suggest that complex formation is the major pathway at a mean collision energy of 1.5 eV, a finding which is consistent with kinetic data at low to moderate temperatures, [6][7][8][9][10][11][12] and with the conclusions based on the bulb and HBr¯N 2 O van der Waals complex experiments of Wittig and co-workers. [13][14][15][16] In this article we turn our attention to the rotational angular momentum polarization of the OH reaction products. 17 For three-atom systems, it is becoming increasingly clear that product rotational polarization measurements can provide detailed mechanistic information, as foretold in the early work of Herschbach and co-workers.…”

Femtochemistry of bimolecular reactions from weakly bound complexes: computational study of the H + H′OD → H′OH + D or HOD + H′ exchange reactions

“…The first experiments of this kind carried out by Zewail's group involved the complexes (HI) • • • (CO 2 ) 15,16 and (HBr) • • • (I 2 ) 17,18 . Since then, this and other groups explored or revisited this class of reactions [19][20][21][22][23][24] and similar ones relying on charge transfer between the moieties of the complex upon photoexcitation by the pump pulse. [25][26][27][28][29][30] One of the prototypical examples of bimolecular reactions is the pair of exchange reactions:…”

Rayleigh wave at the boundary of an inhomogeneous nonlinear viscoelastic half-space

“…For the discrete wave spectrum, the most complete and rigorous procedure of the equation derivation was considered in [3], where an infinite-dimensional system of differential equations was obtained for complex amplitudes of weakly nonlinear surface waves. In the derivation of equations for the continuous wave spectrum in [6][7][8][9][10][11][12][13], it was assumed that low-frequency components are absent in the spectrum of the wave, which restricts the area of applicability of the obtained equations.In [15][16][17], a more universal approach is used for the derivation of equations for nonlinear Rayleigh waves, which is based on a regular procedure of the transition to normal variables corresponding to the nonlinear boundary-value problem [18,19]. This approach is free of any limitations on the spectral composition of the waves described.…”

“…The derivation of equations for nonlinear Rayleigh waves has been considered in a number of works for both the discrete [3][4][5] and continuous [6][7][8][9][10][11][12][13] wave spectrum. The most comprehensive review of these works can be found in [14].…”
