Abstract

{We present a complete analysis of the hyperfine structure of the MnH A 7-PI-X 7-SIGMA+ (0,0) band near 5680 angstrom, studied with sub-Doppler resolution by intermodulated fluorescence spectroscopy. Magnetic hyperfine interactions involving both the Mn-55 (I = 5/2) and H-1 (I = 1/2) nuclear spins are observed as well as Mn-55 electric quadrupole effects. The manganese Fermi contact interaction in the X 7-SIGMA+ state is the dominant contributor to the observed hyperfine splittings; the DELTA-F = 0
