Abstract
The $B \rightarrow X$ (3050 {\AA}) and $D \rightarrow $X(2350 {\AA}) band systems of XeCl are photographed using sources containing both natural $Cl_{2}$ and isotopically pure $^{35}C1_{2}$. The spectra permit us to refine the existing vibrational analysis of the $B \rightarrow X$ laser transition and obtain a complementary analysis of the $D \rightarrow X$ transition. The results show that the D state has smaller $R_{e}$ larger $\omega_{e}$, and larger $D_{e}$ than does the B state, as is found also in XeF. Higher $v^{\prime\prime}$ levels are observed in the $D\rightarrow X$ spectrum, permitting us to obtain a more precise estimate of $D_{e}^{\prime\prime}$ than was obtained previously from the $B\rightarrow X$ system alone.
