Directl-Type Doubling Transitions in ClCN

Abstract

Direct $l$-type doubling transitions have been observed in ${\mathrm{Cl}}^{35}$ ${\mathrm{C}}^{12}$ ${\mathrm{N}}^{14}$ for $J=17, 18, 19, \mathrm{and} 23$. A formula has been constructed for the $l$-type doubling constant: $q=7.467467-1.327\mathrm{}\times {10}^{-5\mathrm{}}J(J+1\mathrm{})\mathrm{}$. The absolute value of the asymmetry parameter $\eta$ was determined to be 0.0101±0.0004.
