Atomic Emission Spectra of Neutral Noble Gases in the Infrared Spectral Range This book is an invaluable guide to calibrating any infrared spectrum using noble gases as a reference. Featuring a detailed graphical and tabular overview of highly excited (Rydberg) states of neutral noble gases in the infrared range of 700–7000 cm 1 it helps researchers by providing high precision experimental data that can be used in almost every infrared spectroscopic laboratory. Chapter 1 Introduction Chapter 2 Experimental setup and spectral analysis Chapter 3 Spectra Chapter 4 Conclusion.
