The Impact

Abstract Theoretical vibrational spectra of indole (IND) and its binary combination with dichloromethane (DC) in various solvents were computed to track the impact of molecular interactions on drug spectral characteristics. When transitioning from plain drug to complexes, 3561.26 cm− 1 mode of the IND displays a substantial shift in peak location. The 3561.26 band shows (~ 15.58) red shift upon dilution. The geometry of drug and IND-DC complex in various solvents was calculated using quantum chemical calculation utilizing DFT.

Temperature Dependences

Conformational mobility of tetruloses, 2-pentuloses, D-3-pentulose and 4-deoxy-L-pentulose was studied by measuring temperature dependences of CD spectra in the region +40°C to -140°C in a methanol-ethanol (1:4) mixture. The changes in spectra reflect the population of rotamers around bonds to the carbonyl chromophore. The most stable conformers were determined by PCILO quantum chemical calculation.
