Renner–Teller and Spin–Orbit Interactions between the Ã2A1 and the X̃2B1 States of NH2: The Stretch-Bender Approach

Photodissociation of ND3 and ND2H at 193.3nm: Symmetry dependence of the rotational distributions and vibrational excitation of the ND2 () fragment

“…In order to demonstrate this we have made use of the Renner-Teller calculations which we used previously in our study of the fragmentation of ND 19 3 . This uses the stretch-bender model developed by Alijah, Jungen and Duxbury, and used for model calculations of the spectrum of NH 2 [22][23][24].…”

Renner–Teller interaction, high angular momentum states and spin-orbit interaction in the electronic spectrum of ND2

“…The basis of this is described in detail by Duxbury et al [31] and by Alijah and Duxbury [32]. The stretch-bender part of the Hamiltonian originated from an idea of Jungen, who together with Palivan developed its use for linear molecules, as well as for CH 2 [31].…”

“…In table 2 we give the excited state term values derived from the experimental measurements of transitions in the 2 0 0 and 2 0 1 bands by using the v 2 ¼ 0 and 1 term values obtained from the work of Muenchausen et al [35] and Morino and Kawaguchi [36]. In this table they are compared with theoretical calculations based upon the NH 2 spectrum [33,34], using the stretch-bender Renner-Teller Hamiltonian [32]. In table 3 we show the ground state term values derived from the earlier experimental work, and in table 4 the term values of levels of the higher vibrational states of the ground electronic state.…”

“…However in their paper only an outline of the rotational analysis was given. In the present paper we have extended the analysis by making use of stretch-bender [31,32] calculations of the spectrum of ND 2 , using the potential developed by Alijah and Duxbury [33,34] in their detailed modelling of the NH 2 spectrum. We have also used the rotational term values of ND 2 derived from the analysis of high resolution laser magnetic resonance, electronic spectra, and microwave optical double resonance, by Muenchausen et al [35], and the very high angular momentum states measured in their far infrared FT spectra by Morino and Kawaguchi [36].…”

“…The stretch-bender part of the Hamiltonian originated from an idea of Jungen, who together with Palivan developed its use for linear molecules, as well as for CH 2 [31]. In the present paper we have made use of the parameterisation used by Alijah and Duxbury [32][33][34] to fit the extensive data on the ground and excited states of NH 2 . The parameters Figure 3.…”
