✦ Synopsis

The analysis of measured hyperfime splittings in the 'El2 -%'A, spectrum of NOa shows that the major cause of the observed hfs splittings in the excited 'Bz state is vibronic coupling between a single level 01 thc'B2 state and many high lying vibrational levels of the z*A, ground state. Only a minor part of the hfs splitting may be due to spin polarization of the core. These results agree with the simple MO picture of NO:! which predicts no Fermi interaction type hfs in the pure *B2 state.
