Microhydration Effect on Properties of First Branched Interstellar Molecule (i-PrCN)
In this work, we have focused on microsolvation of isopropyl cyanide (i-PrCN) as isopropyl cyanide has been recently detected in interstellar space and is of great importance from the astrochemical and bio-chemical point of view for its branching carbon chains.
Such branches are needed for many molecules crucial to life, such as the amino acids that build proteins. The phenomenon of the formation of hydrogen bond affects structure, energetic and electric properties of microhydrated isopropyl cyanide and this has been explored by using three different quantum chemical models. It is observed that the structural parameters calculated by the three models display similarities, however model dependence is evident from equilibrium electronic energies of the clusters. Presence of water molecule has a significant effect on the values of dipole moments and polarizabilities. Rayleigh intensities which are calculated using mean polarizibility and polarizibility anisotropy are increased much due to the formation of hydrogen bonding. For CN stretching vibration of isopropyl cyanide, intensification of Raman scattering activities are observed upon complexation.
