White Papers (Position Papers) on Mineralogical Infrared Spectroscopy Theory
Free from Kasper Jasper Press
Does Infrared Spectroscopy Report on Mineral Crystal Structure? 
Can mineral bands be summed to explain water bands as overtones? No, water bands with no recognizable fundamental bands occur all the time. Here is a case study. 
Can the 5200 and 4500 cm-1 bands tell us about free and OH mineral water? Well, 4500 is not OH Water, it is CaOH water.
