Abstract
The microwave spectrum arising from transitions between Zeeman levels in the , state of nitric oxide is reinvestigated with particular regard to the lambda doubling which is observable for electric-dipole transitions. This doubling is compared with the theory of Karnaugh. The experiments also give a new and improved determination of the nuclear hyperfine coupling constants and of the molecular splittings. The theory of the hyperfine effect is reexamined in detail.
