Isotope effects on band intensities in the B I-2 (+)-X pound I-2 (+) pound system of GaO isotopomers
MetadataShow full item record
Relative intensities of eight vibronic bands, belonging to the Delta upsilon = -2 sequence of the B I-2 (+) pound -X I-2 (+) pound electronic transition of four GaO isotopomers have been measured and interpreted in terms of possible isotope effects on the parameters governing the band intensity. Obtained results showed very small isotope effect on the Franck-Condon factors and r-centroids and revealed that the observed intensity ratios of the corresponding isotope bands are controlled mainly by the isotope abundance of Ga-69 and Ga-71 in natural gallium.
