Abstract

Fourier transform infrared emission spectra of MnH and MnD were observed in the ground X(7)Sigma(+) electronic state. The vibration-rotation bands from v = l --> 0 to v = 3 --> 2 for MnH and from v = 1 --> 0 to v = 4 --> 3 for MnD were recorded at an instrumental resolution of 0.0085 cm(-1). Spectroscopic constants were determined for each vibrational level and equilibrium constants were found from a Dunham-type fit. The equilibrium vibrational constant (omega(e)) for MnH was found to be 1546.84518(65) cm(-1), the equilibrium rotational constant (B-e) is 5.6856789(103) cm(-1) and the eqilibrium bond distance (r(e)) was determined to be 1.7308601(47) Angstrom.
