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

摘要

A rotational and vibrational analysis has been made of the ND2 (A) over tilde (2) A(1) -(X) over tilde B-2(1) emission spectrum produced from the ultraviolet laser induced dissociation of both jet cooled and room temperature deuterated ammonia. By a combination of these experimental data with model calculation based upon the stretch-bender Renner-Teller Hamiltonian, and a previous analysis of the NH2 spectrum, most of the strong features in the emission spectra have been assigned. The spectrum consists of transitions from a narrow distribution of high angular momentum states peaking at K-a values of 7 in the jet condition, and 8 at room temperature. Information has also been gained on the high angular momentum states of previously inaccessible higher bending levels from v(2)=2 to v(2)=6 in the (X) over tilde B-2(1) state.
