“The A-X bands of A10 have been obtained from a hollow-cathode discharge and at a resolving power exceeding 200,000. The doublet splitting of the P-branch of the $O-O$ hand has been observed down to $K=7$. From standard analysis of the doublet separations the splitting constants have been found to be $\gamma \prime =0.016\pm 0.005$ $cm-1$ and $\backslash gamma^\{\backslash prime\}^\{\backslash prime\}\; =\; 0.004\; \backslash pm\; 0.005$ $cm-1$. Derived inertial constants are in agreement with those of $Pomeroy.1$”
