It is now more than fifty years ago that Felix Bloch and Edward Mills Purcell independently discovered a phenomenon called nuclear magnetic resonance (NMR). Only a few years later, in 1952, both received the Nobel Laureate Physics award for this discovery. Purcell and Bloch were the first to “listen” to the whisperings of hydrogen. They eventually obtained an NMR spectrum representing the different “pitches” of the nuclei, a property, which reflects the physico–chemical (electronic) neighbourhood of the nucleus.

Chemical imaging spectroscopy is an exciting new analytical advance that answers commonly asked questions such as what chemical species are in a sample, how much of each is present, and most importantly, where are they located? Through the fusion of traditional infrared spectroscopy with powerful microscopic and macroscopic imaging capabilities, chemical imaging spectroscopy answers all these questions simultaneously, in a single rapid measurement.

As regular readers of this column will know there have been reports at irregular intervals on the ongoing attempt to establish an international spectroscopic data bank. The concept is based on the successful protein crystallographic data bank (PDB) into which the key electronic coordinate data is placed following almost ever peer-reviewed protein crystallographic publication. This databank is then made available to the crystallographic community and is a key resource for those active in this field.

Ever since the development of inductively coupled plasma-mass spectrometry in the mid 1980s, there have been certain applications or specific analyses that have been regarded as difficult or impossible to address using the technique. This article explores the optimisation of the technique in high matrix samples.

In the final article of this series on new Internet-based services for the chemist/spectroscopist, I will be taking a quick look at the ACD/Labs I-Lab online web-based program range.
