| Abstract: | Fourier transform infrared emission spectra of MnH and MnD were observed in the ground X7Σ+ electronic state. The vibration-rotation bands from v = 1 → 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 (ωe) for MnH was found to be 1546.84518(65) cm−1, the equilibrium rotational constant (Be) is 5.6856789(103) cm−1 and the eqilibrium bond distance (re) was determined to be 1.7308601(47) Å. |
