Abstract

A molecule of 2-chloro-4, 5-dimethyl-1, 3, 2-dioxaphospholene is an asymmetric top the with parameter of asymmetry K=-O.75, i.e. near prolate symmetric top. The dipole moment component b=° due to molecular symmetry (Fig.1). Rotational transitions corresponding to the dipole moment component 11 are permitted. Pure rotational transitions corresponding to i may be a c forbidden by symmetry. The spectrum is peculiar by its band structure. Sufficiently narrow and line crowded bands conform to transitions of J J+1, t a type for every value of 3. It is a matter of difficulty to identify spectral lines (rotational transitions) because:
