C. Mande et Vg. Asolkar, DEPENDENCE OF ROTATIONAL-CONSTANTS OF DIATOMIC HALIDES ON ELECTRONEGATIVITY, Indian Journal of Pure & Applied Physics, 34(1), 1996, pp. 47-48
Dependence of the values of rotational constants (Be) of the group IA
diatomic halides upon the electronegativity difference (Delta chi) of
the constituent atoms has been shown. An advantage of this method is t
hat different halides can be brought into a single fold so far as the
rotational property of molecules is concerned.
