1Ab initio molecular dynamics investigation of structural, dynamic and spectroscopic aspects of Se(vi) species in the aqueous environment.

Borah S1, Padma Kumar P.

Phys Chem Chem Phys. 2016 Jun 7;18(21):14561-8. doi: 10.1039/c6cp01835a. Epub 2016 May 16.

Microscopic investigation of solvation of selenic acid (H2SeO4) in the aqueous environment has been carried out using the Car-Parrinello molecular dynamics simulation technique. The species deprotonates to HSeO4(-) in a few picoseconds owing to its low pKa1 value of -3.0. A dynamic equilibrium between HSeO4(-) and SeO4(2-), is observed in qualitative agreement with the reported pKa2 value of 1.70. The governing deprotonation mechanism and the structural and dynamic evolutions of the system, particularly the nature of hydrogen bonding, their strengths and lifetimes are investigated comprehensively.
