Spectroscopy is rapidly evolving into an integrated, intelligent ecosystem where advances in instrumentation, detectors, and optics—combined with chemometrics and artificial intelligence (AI)—are enabling higher sensitivity, miniaturization, multimodal analysis, and real-time decision-making across techniques ranging from ultraviolet–visible (UV–vis), infrared (IR), and Raman to inductively coupled plasma mass spectrometry (ICP-MS), laser-induced breakdown spectroscopy (LIBS), and X-ray fluorescence (XRF). Together, these developments are driving automation, predictive modeling, and the emergence of autonomous analytical laboratories with increasingly connected, cloud-enabled workflows.
Brian Smith offers a review of the C-H stretching and bending vibrations of methyl and methylene groups and then discusses how to use infrared spectroscopy to determine some of the branch points found in alkanes.
Researchers have found that LIBS spectroscopy models trained on compressed rock pellets produce inaccurate compositional readings when applied to fine-grained loose powders, raising concerns for planetary missions analyzing Martian soils.

Studying archaeological bone is important to learning more about the historical biological record that artifacts alone cannot tell us. Christina Ryder, a postdoctoral researcher at Texas A&M University, explains how to obtain the best collagen signals when studying archaeological bones.
There are numerous soft and technical skills spectroscopists need to have to serve as an analytical laboratory manager. Saikat Banerjee, who serves in this role at DuPont, explains what these skills are and why they are essential.

What predictive modeling strategy works best for radiocarbon dating? According to Christina Macie Ryder, a postdoctoral researcher at Texas A&M University, random forest (RF) models perform better than other modeling strategies such as partial least squares regression (PLSR).
Over the past two years, molecular spectroscopy has undergone a marked transformation from a predominantly laboratory-based analytical approach into a field-deployable, data-rich forensic toolkit. This evolution has been driven by three converging trends: (i) advances in vibrational spectroscopic instrumentation (Fourier transform infrared [FT-IR], Raman, and near-infrared [NIR], (ii) the integration of chemometrics and machine learning for extracting actionable information from complex spectra, and (iii) the emergence of portable and miniaturized devices suitable for in situ analysis. The ten papers reviewed here collectively demonstrate how spectroscopy is now addressing some of the most persistent challenges in forensic science—such as time since deposition (TSD), post-mortem interval (PMI), trace evidence discrimination, and rapid drug identification—while maintaining evidentiary integrity through non-destructive analysis. Importantly, these works also reflect a shift toward interpretability, validation, and legal defensibility, which are essential for courtroom acceptance.
Why is near-infrared (NIR) spectroscopy a more useful technique when studying archaeological bone? According to Christina Macie Ryder, a postdoctoral researcher at Texas A&M University, it comes down to the penetration depth.
