ABSTRACT

The physical principles underlying infrared spectroscopy have been appreciated for more than a century. As one of the few techniques that can provide information about the chemical bonding in materials , it is particularly useful for the nondestructive analysis of solids and thin films, for which there are few alternative methods. Liquids and gases are also commonly studied , more often in conjuction with other techniques. Chemical bonds vary widely in their sensitivity to probing by infrared techniques.
