Abstract
Woods band at 3840 {\AA}, Variously attributed to $Sio^{+1,2,3}$ and $SiN,^{4}$ has been conclusively shown to belong to $SiO^{+}$ from it s isotope shift with $^{18}O$. Rotational constants and spin splitting constants of the upper and lower $^{2}\Sigma$ states have been obtained from the 0-0 and 1-1 bands for both isotopic species. A good estimate of $\omega_{O}{^{\prime}}$ and $\omega_{O}{^{\prime\prime}}$ from these data allows the identification of these states with the $B^{2}\Sigma$ and $X^{2}\Sigma$ states of $SiO^{+}$ recently found by E. A. Colbourn $et al^{5}$ in their photoelectron spectroscopy work.
