Vibrational spectroscopy Vibrational Spectroscopy (IR, Raman)
www.chemie-biologie.uni-siegen.deSpectroscopy (IR, Raman) Vibrational spectroscopy Vibrational spectroscopy is an energy sensitive method. It is based on periodic changes of dipolmoments (IR) or polarizabilities (Raman) caused by molecular vibrations of molecules or groups of atoms and the combined discrete energy transitions and changes of frequen-cies during absorption (IR) or
Gas Chromatography-Mass Spectroscopy
cires1.colorado.edumass spectroscopy characterizes each of the components individually. By combining the two techniques, ... charged molecule which remains intact is called the molecular ion. Instability in a molecular ion, due to the energy imparted by the electron impact, can cause that ion to break into smaller pieces (fragments).

Infrared Spectroscopy 1. Introduction
www.ifsc.usp.brInfrared spectroscopy exploits the fact that molecules have specific frequencies at which they rotate or vibrate corresponding to discrete energy levels. These resonant frequencies are determined by the shape of the molecular potential energy surfaces, the masses of the atoms and, by the associated vibronic coupling.

www.philadelphia.edu.joFlame and Plasma Emission Spectroscopy are based upon those particles that are electronically excited in the medium. The Functions of Flame and Plasma 1. To convert the constituents of liquid sample into the vapor state. 2. To decompose the constituents into atoms or simple molecules: M+ + e-(from flame) -> M + hn 3.
