A critical analysis highlighting the most innovative contributions ______________________________________________________________________________ Dr.Suresh C. Mehrotra, FNASc, FIETE, AvHF, has received Ph.D. degree having the thesis entitled “ Collision induced transitions between molecular rotationa levels” under Professor James E. Boggs from the University of Texas at Austin, USA in July 1975 after completing his postgraduate education (1970) from Allahabad University. He has been actively involved in teaching and research for last four decades. He has made significant and pioneering contributions in (a) establishment of a novel time domain nonresonance spectrometer to cover wide frequency range of 10 MHz to 20 GHz (b) understanding ordering of molecules in polar binary liquids of different types and (c) theoretical and experimental advances to rotational relaxation in gas phase. In the first decade (1970-80), his contribution was to improve convergence of the time dependent perturbation theory [4] and to apply it to Inelastic Scattering theory to explain J-dependence of spectral line shapes related to rotational transitions in many molecules [6] of interstellar significance [10,12,13-17]. Experimental discrepancies regarding J-dependence have been explained using the theory. The second decade (1980-90) was devoted to experimental and theoretical studies about coherence decay rates (T2 ) and population transfer rates (T1) [30,38] in rotational transitions in gas phase. Earlier to the nominee work , it was general understanding that T1- type relaxation times are generally equal to corresponding T2-type relaxation times indicating dominance of inelastic collisions in gas phase. For the first time ,the nominee shows that the values of T1/T2 lie between 1 and 2 [25] for different inversion lines of NH3. This was explained due to inelastic collisions between the levels under consideration. Not only that , Investigation carried out by the nominee shows that the values of T1 are more than the corresponding values of T2 for l-doublet transitions of HCN perturbed by H2 ,D2 and He indicating dominance of elastic collisions [33]. The theoretical details reveal that this was elastic collisions consists of two inelastic half collisions. He has also provided solutions of four level Bloch type equations to explain transient pulse experiments [38, 40 ]. In the Third decade and fourth decades (1990-2009), the focus has been shifted from gas phase to liquid state using broadband microwave permittivity spectroscopy using time domain technique [42] (first and only in India). The time domain reflectometer along with bilinear calibration procedure has been developed to get permittivity spectra in frequency range of 100 MHz to 20 GHz. The coaxial[47] cell as well as cells based on microstrip lines[100,102] (first time,not used earlier) were used for transmission of picoseconds pulses. Simulation software (first time) were developed for determination of permittivity spectra. This experimental development was unique and has been highly appreciated by the sponsored agency (DST).
