✦ Synopsis

By means of a D v and D B formalism for correction parameters, expressions were derived for higher-order Dunham coefficients, Y * £J 04 , Y * £J 12 , and Y * £J 21 , in which contributions of the breakdown of the Born-Oppenheimer approximation were taken into account. Including Y * £J 04 , Y * £J 12 , and Y * £J 21 , and Dunham's Y 09 , Y 17 , and Y 25 coefficients in addition to the lower-order Y * £J ij

and Y k1 in the analysis, an extensive data set of the vibrational-rotational and the rotational transitions for four isotopomers of lithium hydride was fitted simultaneously to a single set of molecular constants within experimental errors. Since lithium hydride is a very light molecule, expressions shown in the present article should provide a means applicable to most cases of the spectral analysis of diatomic molecules in the 1 S state.
