Title: U.V. SPECTRA OF InO AND $InO^{+}$
Creators: Balfour, W. J.; Saksena, M. D.

Abstract: The emission spectrum of InO has been recorded using different excitation sources: a microwave discharge through a flowing mixture of $InCl_{3}$, $O_{2}$ and argon; a hollow cathode; and an indium metal d.c. arc in air. Twelve bands belonging to the $\Delta v = +1$ and 0 sequences of a $^{2}\Sigma - ^{3}\Sigma$ transition have been observed. The 0-0 and 1-0 bands lying respectively at 428.2 and 416.5 nm have been examined at high resolution and show marked effects of nuclear hyperfine coupling. The $InO^{+}$ spectrum was also excited in the d.c, arc and microwave discharge experiments. Seven bands belonging to a $^{1}\Pi - ^{1}\Sigma$ transition in the 370 - 390 nm region have been assigned. For both InO and $InO^{\ast}$ accurate vibrational and rotational constants have been determined for the first time.
