Inner-shell X-ray absorption spectra of the cationic series NHy+ (y = 0–3)

“…Experiments on molecular ions addressed the valence electronic structure of NH 2 + using VUV photoionisation 34 or the determination of the absolute cross section of NH + using electron impact ionisation. 35 Yet, there is no detailed information available on the inner-shell XAS of the cationic series NH y + apart from the atomic cation, N + , which has been studied previously by Gharaibeh et al 36 Furthermore, the role of NH y with different numbers y of hydrogen atoms has recently been studied in the liquid phase by Ekimova et al for alkylamines in different solutions. 37,38 They show a strong dependence of the N 1s X-ray spectra on the number y of H atoms and the solution itself.…”

Kinetic-energy release of fragments from electron-impact dissociation of the molecular hydrogen ion and its isotopologues

“…(16) and (21) Fig. 3 we present our BD weighted KER cross sections for the 2pσ u and 2pπ u states using the same approximations.…”

“…Many experimental measurements of the KER cross sections have been used to extract scattering cross sections [8][9][10][11][12][13][14][15][16][17][18], identify dissociative processes [8][9][10][11][12][13][14][15][16][17][18], and to determine experimental conditions [18][19][20], molecular structure [21,22] and collision dynamics [21]. The KER cross sections can be extracted from a complete close-coupling calculation that includes all degrees of freedom (electronic, vibrational, and rotational).…”

Dipole moments of HCO+and NH+from cyclotron frequency polarizability shifts

“…Here, we applied the method to the astrophysically important ion HCO + (the formyl cation) [3][4][5] and to NH + , which we chose because it was predicted by Cheng et al [6] to have a particularly large polarizability. NH + is believed to be important in the formation of ammonia in interstellar molecular clouds [7,8].…”
