A computational technique within the Extended Hückel frame-work for the calculation of the hydrogen-molecule interaction energy is described. The procedure is ten times faster than the usual diagonalization procedure.The algorithm consists of transforming the generalized secular equation to give a bordered-diagonal matrix secular equation, which is solved by means of an efficient bisection technique.As an example, two problems are discussed: (i) glycine intra-molecular proton transfer process; (ii) interaction of the molecular fragments CH and OH.An atomic SCF Gaussian basis set was used instead of the usual Slater type basis set.
