Transmission Reflection Absorption Luminescence Elastic Scattering Inelastic Scattering Raman, Fluorescence and IR Absorption Scattering and emission Absorption As discussed, when an atom or molecule is brought into an electric field E , an electric dipole moment is induced in the system. Raman Spectroscopy. He then joined University of Pennsylvania, Philadelphia, USA in 2002 and completed his Ph. It thus generates a coherent Stokes wave in phase with the incident fields. 5.33 Lecture Notes: Introduction to Spectroscopy Page 3 2) Emission: Excitation induces emission of light from the sample (usually of different frequency). field so rapidly that the gain for the weaker Stokes lines gets suppressed (see equation 29.5). Raman Spectroscopy In Raman work the rotational quantum number changes by 2 units rather than one is related to the fact that the molecular polarizability, in contrast to the permanent dipole moment; is not a vector quantity, and so in every complete rotation, it returns twice to its original value. Electromagnetic radiation covers a wide range of frequencies from gamma rays to radio frequencies. Journal of Raman Spectroscopy 2016, 47 (12) , 1540-1547 . The exam is optional for a fee of Rs 1000/- (Rupees one thousand only). Mohamed Shabana. Spatial evolution of the Stokes wave propagating through the Raman active medium.

This fact has posed several restrictions to the progress of Raman spectroscopy and had configured to a large extent the instrumentation since the beginning of the experimentation to the present. Week 2. PREPARE BY: Bhaumik R Bavishi (15MPH301) NIRMA UNIVERSITY ; CONTENTS INTRODUCTION PRINCIPLE INSTRUMENTATION DIFFERENCE BETWEEN RAMAN VS IR METHODS TYPES APPLICATION INTRODUCTION Raman spectroscopy was discovered by C. V. Raman in 1928 It is a spectroscopic technique used to observe vibration , rotational, and other low-frequency modes in a system. Note: This exam date is subjected to change based on seat availability. from IIT Bombay in 1999. Specically, Raman spectroscopy is concerned with the latter, the absorption and emission The term "Raman spectroscopy" is an abbreviation of "Raman scattering spectroscopy". Dr. Bagchi works on understanding the roles of interactions and dynamics in molecular systems using novel spectroscopic techniques.

I am a Professor of Chemistry in IIT Bombay, with research interest in ultrafast spectroscopy and time resolved fluorescence microscopy. Basic knowledge of Raman spectroscopy can be gained by understanding the meaning of three words: "spectroscopy", "scattering", and "Raman". Let us consider the following two cases. In electronic excited states, unlike in the ground state, the chemistry is largely governed by the crossing of potential energy surfaces or more generally by the coupling of multiple electronic states via nuclear motion.

More details will be made available when the exam registration form is published. It will be e-verifiable at. (PDF) RAMAN SPECTROSCOPY - ResearchGate When light falls on a sample, a small part of it gets scattered in dier-ent directions. Initiative by : Ministry of Education (Govt of India). For very intense light fields, available from lasers- now onwards we will call it the pump field- apart from the increased spontaneous, Raman scattering, another process called the stimulated Raman scattering occurs.
