semiempirical

A semiempirical downscaling approach for predicting regional temperature impacts associated with climatic change.

“Using semiempirical models of densification applied to past Vostok climate conditions, Barnola et al. 1991 reported that the age difference between air and ice may be ~6000 years during the coldest periods instead of ~4000 years, as previously assumed.”

I apply a variety of computational methods, semiempirical and nonempirical, as well as qualitative arguments, to problems of structure and reactivity of both organic and inorganic molecules of medium size.

In the second approach I have analyzed, with the aid of various semiempirical methods, the molecular orbitals of most types of reactive intermediates in organic chemistry-carbonium ions, diradicals, methylenes, benzynes, etc.
