The Absorption Spectrum of InCl

Abstract

A study of the band spectrum of InCl has been carried out in absorption with a determination of vibrational, rotational, and electronic energy levels associated with the band system in the region 2650 to 3000 angstrom units. The ${B_v}^{\prime }$ and ${B_v}^{\prime \prime }$ values were found to be of the order of 0.11 wave numbers, from which can be calculated a nuclear separation of the order of 2.3×${10}^{-8\mathrm{}}$ centimeter. Predissociation in the band system provided a value for the energy of dissociation of the ground state between 4.64 and 4.66 electron volts.
