Molecular Constants of the 2\(^1\Pi\) State of \(\text{NaLi}\) Molecule

Nguyen Tien Dung, Le Canh Trung, Dinh Xuan Khoa, Nguyen Huy Bang


We report our determination of molecular constants for the 21Π state of NaLi from set of 732 spectral lines. Using the linear least-squares fitting method, an optimum set of molecular constants, which corresponds to dimensionless root mean of squares of deviation σ = 0.62 within 0.1 cm-1 experimental uncertainty, have been derived.
