Abstract

Hyperfine coupling constants for the excited A3Π state of PH were measured for the first time. Detailed information about the electronic wave function of PH in the excited electronic state was extracted. Comparison with similar information available for the same excited electronic state of the NH radical indicated broad similarities in the electronic structure with some differences in detail. The analysis of the hyperfine constants also indicated some shortcomings in the interpretation.
