Optical and related properties of certain Penicillin class of compounds

Antibiotics are the subgroup of organic anti-infective agents that are derived from bacteria or that are toxic to other bacteria. The molecular polarizabilities of a few penicillin group of compounds are estimated by semi-empirical δ-function model and molecular vibration methods. Diamagnetic susceptibilities and Electron ionization cross-sections of these molecules are also evaluated. The results are discussed in relation to bond properties.
