The newest semiempirical method is Semi-Ab initio Model 1 (SAM 1) by Dewar et al. [83]. As the acronym suggests, it is based on AML The two-electron integrals (jiv (tt), however, are calculated analytically over Gaussian-type functions and scaled empirically. Up to the present, no comprehensive list of SAMI parameters and error...
