Question
Chapter 17, Problem 17.12QAP
Interpretation Introduction
Interpretation:
The thickness of the polystyrene film should be determined.
Concept introduction:
The path length is a distance travelled by the light through a sample of analytical cell. It is used in the infrared spectroscopy. The path length can change the sample absorbance without changing the concentration of the sample.
The wave number is also used to calculate the path length of cell. The wave is reciprocal of wavelength of absorption. It is number of wave per unit distance.
