title: The Infrared Handbook
author: William L. Wolfe
description: The Infrared Handbook has been prepared by the Infrared Information and Analysis (IRIA) Center as a replacement for the Handbook of Military Infrared Technology, which was published in 1965. New detectors have been invented, new materials discovered, and many instrumentation techniques undergone vast improvement since then. Therefore, the authors of chapters on radiation theory and sources, detectors, optical materials, optics, and backgrounds have provided updated and expanded replacement chapters. A chapter on displays has been included along with a chapter on infrared tubes, with vidicons and pyroelectric materials emphasized.

  Standard level questions
   1 In the past, single-beam IR spectrometers have 
  been used. These instruments did not have a second 
  beam passing through a reference. Describe the 
  advantage that a double-beam spectrophotometer 
  has over a single-beam instrument.
   2 Consider the description of each of the following 
  infrared absorption bands and suggest a functional 
  group that might be responsible for this absorption.
  a A strong absorption band at 3200 cm–1
  b A reasonably strong absorption band  
  at 2950 cm–1
  c A strong absorption band at 1200 cm–1
  d A strong absorption band at 1725 cm–1
   3 Explain how the mass spectrum of an organic
