$(1 + 1)$ REMPI SPECTROSCOPY OF NO COMPLEXES WITH $N_{2}$, CO AND $CH_{4}$ VIA THE $\tilde{A}$ STATE

Author Institution: Department of Physics, School of Chemistry, Physics and Environmental Science, University of Sussex; Spectroscopy of Complexes and Radicals (SOCAR) Group, School of Chemistry, Physics and Environmental Science, University of SussexThe spectra of the $\tilde{A}\leftarrow\tilde{X}$ transition of the $NO\cdot X$ molecular complexes, where $X = N_{2}$, CO and $CH_{4}$, have been recorded using one-color $(1 + 1)$ REMPI spectroscopy. The spectra exhibit vibronic features, which are interpreted as hindered internal rotation and the underlying end-over-end rotational structure. Some insights into the structure of the spectra are gleaned from ab inition calculations
