Resonance Enhancement of Raman Spectroscopy: Friend or Foe?
By Fran Adar
The presence of electronic transitions in the visible part of the spectrum can provide enormous enhancement of Raman signals.

Logger Rhythm
By David W. Ball
A logarithm is a mathematical function that shows up in some forms of spectroscopy. Understanding what it is can give us a better appreciation for its function in our fields.
Calibration Transfer, Part III: The Mathematical Aspects
By Jerome Workman, Jr. , Howard Mark
Calibration transfer is a series of techniques used to apply a single spectral database, and the calibration model developed using that database, to two or more instruments. Here, we review the mathematical approaches and issues related to the calibration transfer process.

NIR Model Transfer Based on Wavelet Transform Algorithms
By Ju Xiang Wang , Zhi Na Xing , Jun Qu
A study is presented that uses an amine mixture as an example to discuss the combination of wavelet and piecewise direct standardization algorithms, which will improve the precision of near infrared (NIR) model transfer.

Out of This World: The Next Generation of Medical Diagnosis
Real-time air fingerprinting (RAFT) uses spectroscopic techniques to measure volatile organic compounds. Now, the University of Leicester in the UK is testing the use of RAFT for rapid and noninvasive diagnosis of illness in an emergency ward. Paul Monks, a professor in atmospheric chemistry and earth observation science, explains the approach.
