In this review article, the editors of Spectroscopy break down the most recent research and trends using inductively coupled plasma mass spectrometry (ICP-MS).

We wrap up our discussion of the mid-infrared spectra of inorganic compounds by looking at the spectra of silicates, nitrates, and phosphates. We will see that silicates have complex surface chemistry, and that infrared spectroscopy can tell us something about this. We will note that, of the five families of inorganics examined, the wavenumber ranges for the polyatomic anion stretching peaks in several of these functional groups overlap. However, polyatomic anion bending vibration peaks can be used to distinguish the five types of inorganics studied.

As one of the first renowned women spectroscopists, Craver broke down barriers in the field and is recognized for her work compiling reference libraries of spectra that set the foundation for modern infrared (IR) spectroscopy.

Narangerel Altangerel, Zhenhuan Yi, and Marlan Scully of Texas A&M University recently used TRIP to analyze eight protein–ligand systems. Spectroscopy recently spoke to these three researchers about their findings and what the implications are for high-throughput drug screening.

The editors of Spectroscopy gathered information about the average salaries and compensation packages compared to previous years. We report on these findings here in our annual salary and employment survey.

To study the effect of various extractants on the structure of peat humic acid, peat humic acid was extracted using NH3·H2O, Na2CO3, NaHCO3, and Na2SO3 via alkali-extraction and acid-precipitation methods.
