Abstract
A Varshni treatment between stretching frequencies and bond lengths is given for 16 heterocycles of the types Hal-M(SCH2CH2)(2)X and Hal-M(C H2CH2CH2)(2)X (M = As/Sb/Bi, Hal = Cl/Br/I, X = O, S, NR). The intensi ties of the Raman emissions for the M-Hal bonds increase in the follow ing order: Cl << Br < I. The slopes of linear fits, bond length vs. (f orce constant)(-1/2), decrease in the following order: Cl > Br >> I. P ractically, the Varshni constants are used to estimate the complementa ry quantity, stretching frequency or bond length, in 35 cases. (C) 199 8 Elsevier Science B.V.
