Happy reading!
By Brian C. Smith
In our “IR Spectral Interpretation” column published in our April/May 2024 print issue, Smith reexamines the beginning and intermediate topics of infrared (IR) spectroscopy. He reviews the information that is contained in an IR spectrum, which includes peak positions, peak heights, and peak width, and how all these bits of information tell us about the structure and concentration of molecules in a sample (1).
Icons of Spectroscopy: An Interview with Jeanette Grasselli Brown, Part I
By Caroline Hroncich
Jeanette Grasselli Brown is undoubtedly an icon of spectroscopy. Her story is one of perseverance—forging a path for herself at a time where few women were able to get ahead in science. Grasselli Brown's expertise includes vibrational spectroscopy, combined instrumental techniques, computerized spectroscopy, process analysis and control, and environmental spectroscopy. Spectroscopy associate editorial director Caroline Hroncich sat down with Jeanette Grasselli Brown to talk about her career in spectroscopy.
She holds 13 honorary degrees, including an Honorary Doctor of Science degree from Ohio University, her alma mater. Grasselli Brown also holds one patent and has published 80 papers and nine books in the field of IR and Raman spectroscopy. She was the editor of the journal Vibrational Spectroscopy from 1989–1995 (2).

In our “Atomic Perspectives” column published in our April/May 2024 print issue, Thomas explores the current landscape of global critical raw materials (CRM) trends in research and the applications of atomic spectroscopy (AS), including inductively coupled plasma–mass spectrometry (ICP–MS), inductively coupled plasma–optical emission spectrometry (ICP–OES), and X-ray analytical techniques in their identification of diverse industrial and environmental media (3).
By Jerome Workman, Jr.
In this article, two distinct baseline correction methods, frequency-domain polynomial fitting, and time-domain molecular free induction decay (m-FID), are compared to determine which approach is more effective in reducing baseline errors in infrared absorption spectra (4).
Unveiling the Link Between Fatty Acids and Neurodegenerative Diseases
By Will Wetzel
Spectroscopy’s 2023 Emerging Leader in Molecular Spectroscopy award winner Dmitry Kurouski and his team recently explored the link between fatty acids and neurodegenerative diseases, examining the potential relationship between LCPUFAs and neurodegenerative diseases like diabetes type 2 and Parkinson's disease (5).
