We show Raman spectra of polymeric fibers acquired as a function of increasing stress and temperature. With knowledge of Raman band assignments, it becomes possible to understand, in detail, the molecular changes that are responsible for polymer orientation and crystallization.

Why Is My Application’s Audit Trail Rubbish?

It has been 20 years since 21 CFR 11 came into effect. And with increased emphasis on data integrity, an audit trail is essential for spectroscopy software. Why then do many audit trails fail to meet regulatory requirements?

Aldehydes feature a unique “lone hydrogen” atom, giving rise to unique C-H stretching and bending peaks, making them easy to spot. In this installment, a new feature is also presented, “IR Spectral Interpretation Review,” where key concepts from past columns are presented for those new to the column and for readers who need a refresher.

Surface-Enhanced Raman Spectroscopy: From Concept to Practical Application

Peer-Reviewed Article

In the last decade, numerous SERS substrates have been developed, but it is difficult to compare and validate their plasmonic performance. In this overview, the authors discuss the three physical parameters of any new SERS platform that must be measured-morphological characterization, optical scattering (far-field response), and near-field properties-and future prospects for the development of new SERS platforms.
