Abstract: <正> We programmed and transplanted some semi-empirical quantum chemistry programs on the pc-1500 pocket electronic computer using BASIC language, mainly including HMO, EHMO, PPP, CNDO and INDO programs. This article introduces the PPP (including closed-shell and open-shell UHF programs) and the EHMO program, which is adapted from the literature [1]. 1. PPP program 1. Basic formula The PPP method is a π electron theory established by Pariser, Parr and Pople, etc. It is based on the Hartree-Fock-Rathaan equation.
