Rotational Analysis of the A2II–X2Σ+ System of MgCl

Nature volume 192, page 1182 (23 December 1961) | Download Citation



ALTHOUGH the internuclear distances in the diatomic halides of the typical elements of Groups I and III are known, often very precisely, few values are available for the diatomic alkaline earth halides. Following the rotational analysis1 of the C2II–X2Σ+ system of CaCl, we have now completed an analysis of the 0–0 and part of the 0–1 bands of the A2II–X2Σ+ system of MgCl, from absorption spectrograms taken in a third order of a 6.5-m. grating instrument.
