Sourav Pal (born 12 May 1955) is an Indian theoretical chemist, former professor of chemistry at IIT Bombay, and former director of the Indian Institute of Science Education and Research, Kolkata. He was a director of the CSIR-National Chemical Laboratory in Pune and an adjunct professor at the Indian Institute of Science Education and Research, Pune.
He has made contributions in the field of coupled cluster-based methods of quantum chemistry. He also developed expectation value and the response properties to multi-reference coupled cluster theory, as well as extended coupled-cluster functions. He has developed a non-iterative approximation to coupled-perturbed Kohn-Sham density functional theoretic equations to calculate non-linear properties.
He has also made contributions in the area of reactivity descriptors; he established Hirshfeld population in the calculation of Fukui functions and developed the local hard-soft-acid-base principle for molecular recognition. He also studied anti-aromaticity in metal clusters.
Education
Sourav obtained his master's degree from the Indian Institute of Technology (Kanpur) in 1977 and his doctorate from the University of Calcutta. He worked at the Indian Association for the Cultivation of Science (IACS). He was subsequently a postdoctoral researcher at the University of Florida with Rodney J. Bartlett in 1986.

Notable research
On hard-soft acid-base relations
He has studied various properties of hardness and softness in relation to molecular properties, like polarizability. In 2002, he identified "Bond Deformation Kernel" to be correlated with interaction-induced shifts in O–H frequencies in halide–water clusters. His model used local polarization, which can be described by normalized-atom-condensed Fukui functions, which is the normal condensed Fukui function multiplied by the number of atoms.
On molecular properties and dynamics
In 1989, he developed theories for describing closed-shell molecules with non-linear electric properties. For open-shell systems, which are marked by a high degree of quasi-degeneracy, he used a multi-determinant description of reference space to formulate a coupled-cluster analytic derivative to compute the non-linear properties. Sourav has also identified the exchange effects as contributions to the static exchange potential of the molecule in electron–molecule scattering. An approximation method to calculate the resonance of molecular anions has been developed by his group. The procedure is based on the analytical continuation method.
In 2003, as an alternative to the Kohn–Sham density functional theoretic approach, which solves the coupled-perturbed Kohn–Sham (CPKS) procedure non-iteratively, Sourav formulated a way to obtain the derivative of the KS matrix using the finite field; the density matrix derivative is obtained by a single-step CPKS solution followed by the analytic evaluation of properties. He has implemented this in deMon2k software and used it for the calculation of electric properties. He also has used Gaussian basis sets and Born–Oppenheimer approximation to study the reactions of molecules. His study led to novel evidence of anti-aromaticity in metal clusters.
