Observations of Two Photon Absorption in Gaseous CaCl. A Study of theD2Σ and X2Σ States

Abstract
In the wavelength region, 616-623 nm, two photon processes have been observed in diatomic calcium chloride. The D 2Σ-X 2Σ transitions of both Ca35Cl and Ca37Cl were obtained. Rotational and vibrational constants have been derived for the D 2Σ and X 2Σ states of Ca35Cl.
