Rather than allowing only one wavelength at a time to pass through to the detector, this technique lets through a beam containing many different wavelengths of light at once, and measures the total beam intensity. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). 185â196, Fourier transform spectroscopy.

INTRODUCTION The total internal energy of a molecule in a first approximation can be resolved into the sum of rotational, vibrational and electronic energy levels. Fourier transform infrared spectroscopy (FTIR) is a spectroscopic technique that has been used for analyzing the fundamental molecular structure of geological samples in recent decades. Raman spectroscopy differs from IR spectroscopy in a few fundamental ways. In a given strong external magnetic field, each structurally distinct set of hydrogens in a molecule has a characteristic resonance frequency, just as each tubular chime in percussion instrument has a characteristic frequency. FOURIER TRANSFORM INFRARED SPECTROSCOPY FT-IR stands for Fourier Transform InfraRed, the preferred method of infrared spectroscopy. The excitation source in Raman spectroscopy is a single wavelength (monochromatic) visible or near IR laser. (FT-IR) Spectroscopy II.
