Optical spectroscopy encompasses a wide variety of techniques used to study how matter interacts with light. Optical spectroscopy techniques are used in physics, astronomy, chemistry, biology, and associated research fields.
Fluorescence guidance is utilized to increase the chances of complete tumour resection while balancing preservation of neurological function in glioma surgery. A multimodal optical microscope capable of imaging the histology and fluorescence of fresh human brain specimens revealed an unexpected pattern of fluorophore accumulation and a new means of visualizing macrophages during surgery.
A high-dimensional photodetection system that combines a lens and a thin-film interface enables simultaneous measurements of light spectrum and polarization states, with the aid of a deep neural network.
Tracking the momentum of scattered electrons reveals the temporal evolution of phonon populations on ultrafast timescales, helping to quantify the contributions of the cooperative electronic–lattice order responsible for phase transitions in quantum materials.
Precision measurement of the dynamical magnetoelectric coupling in an exfoliated van der Waals multiferroic shows a giant natural optical activity at terahertz frequencies.
Sulfur allotropes are proposed to be an important sulfur reservoir in molecular clouds, but spectroscopic data to test this hypothesis are limited. Here the authors measure laboratory far-infrared spectra of cold isolated S8 molecules, which show a near-perfect match with calculations, and examine their fragmentation pathways.

The fundamental knowledge of molecules with magneto-optical properties is still being built as researchers fine-tune their synthesis to optimize their properties. Researchers now add chiral ligands to magnetic heterometallic lanthanide compounds to study their impact on electronic transitions.
