Paperback. Condizione: New. Print on Demand. This book thoroughly examines the infra-red spectrum of helium, a fascinating element with a significant role in atomic structure theories. While this element has been extensively studied, its infra-red spectrum has received comparatively less attention, and this book aims to fill this gap. The author delves into the intricacies of helium's atomic structure, exploring the various series that make up its spectrum. He presents a comprehensive analysis of the principal, diffuse, sharp, fundamental, and combination series, providing detailed insights into their characteristics and relationships. Through a meticulous investigation of the intensity variations of helium's spectral lines with pressure and current, the author uncovers valuable information about the behavior of this element under different conditions. The book also includes a photographic study of the helium spectrum, revealing previously undiscovered lines that further contribute to our understanding of its atomic structure. Overall, this book offers a comprehensive and in-depth exploration of the infra-red spectrum of helium, shedding new light on the properties and behavior of this fundamental element. It is a valuable resource for scientists, researchers, and anyone interested in the intricacies of atomic physics.
