Vitry-Raymond

As part of the same HMO method but with various approximations, appeared the calculations of Zahradnik and Koutecki (117). Vincent and Metzger (118), Vitry-Raymond and Metzger (119), Bonnier and Gelus (120), and Bonnier et al. (121). In 1966, Vincent et al. applied to thiazole the iterative methods restricted to the tt system in the following approximations w" (122), w (123). and P.P.P. (124, 123), This last method was later employed with different approximations and for various purposes by Chowdhury and Basu (125), J. Devanneaux and Labarre (126), Yoshida and Kobayashi (127). Witanowskiet et al. (128). and E. Corradi et al. (129).
