The Remarkable Resilience of Beer's Law
Mark A. Muyskens and Eric T. Sevy
Calvin College, Department of Chemistry, 3201 Burton St. S. E., Grand Rapids, MI 49546

September 1997
Vol. 74 No. 9
p. 1138
Abstract
Described is a case where Beer's law holds to a remarkable degree. Linear absorbance over three orders of magnitude is shown for both pyrazine and 2-methylpyrazine absorption of 266-nm laser light in a 3-m gas cell. The experimental approach is described and discussion includes how the properties of laser light play a role in these results. This case provides a counter-example for a discussion of deviations from Beer's law.
