Dr Govil has to his credit significant applications of semi-empirical quantum chemical theories relating to the conformational aspects of several biological molecules namely, peptides, nucleotides, saccharides, lipids, etc. An important contribution of his, has been in the area of structure of nucleotides based on calculations of conformational energy maps and rotational energy states. He has made precise calculations on the non-bonded and hydrogen-bonded interactions in several important biomolecules. The work of Dr Govil showed the relative contribution of stacking and base pairing in ordered nucleic acids.Dr Govil has done important work in respect of the role of ordered structure of lipids in biomembranes and consequences of structural flexibility and transport properties.
