A technique that is useful in the study of pharmaceutical products and biological molecules, polarization IR spectroscopy has undergone continuous development since it first emerged almost 100 years ago. Capturing the state of the science as it exists today, Linearly Polarized IR Spectroscopy: Theory and Applications for Structural Analysis demonstrates how the technique can be properly... Read more
