Vibrational overtone spectroscopy of molecules containing X-H oscillators
(X = C, N, O...) has become an effective tool for the study of molecular structure,
dynamics, inter and intramolecular interactions, conformational aspects and
substituent effects in aliphatic and aromatic compounds. In the present work, the author studied the NIR overtone spectra of some liquid phase organic compounds. The analysis of the CH, NH and OH overtones yielded important structural
information about these systems. In an attempt to get information on electronic
energy levels, we studied the pulsed Nd:YAG laser induced fluorescence spectra
of certain organic compounds. The pulsed laser Raman spectra of some organic
compounds are also studied. The novel high resolution technique of near infrared
tunable diode laser absorption spectroscopy (TDLAS) is used to record the
rotational structure of the second OH overtone spectrum of 2-propanol. The
spectral features corresponding to the different molecular conformations could be
identified from the high resolution spectrum.
The whole work described in this thesis is divided into five chapters. |
