Abstract
We have recorded and analyzed the high resolution spectrum of the $\nu_{2}$ band of $D_{2}S$ from 740 to $1100 cm^{-1}$. Approximately 670 transitions from $D_{2}^{32}S$ and 130 transitions from $D_{2}^{34}S$ have been assigned. The spectrum was fitted using Watson’s A - form Hamiltonian evaluated in the I-R representation. Ground state constants for $D_{2}{^{32}}S$ were obtained from a simultaneous least squares fit of microwave $lines^{1}$ and our ground state combination differences. Upper state constants were obtained from a least squares fit of the spectral transitions, keeping the ground state constants fixed. Because there were not enough $D_{2}{^{34}}S$ transitions to form ground state combination differences capable of yielding ground state constants, the $D_{2}{^{34}}S$ transitions were fitted using isotopic mass adjustment $terms^{2}$ for upper and lower state A, B, and C and for $\nu_{o}$.
