A spectrometer that directly detects the vibrational “fingerprint” of molecules offers a sensitive new way of deducing a material’s chemical make-up. The device, which was developed by researchers in ...

Infrared spectroscopy is a damage-free method for characterizing biological tissues or cells. With the use of an infrared scattering-type near-field optical microscope (s-SNOM), even the smallest ...

Infrared spectroscopy is increasingly established as a way to carry out in vitro diagnostic testing, thanks to its ability to detect the molecular profiles of many biomarkers. What has been missing, ...

Like infrared (IR) spectroscopy, Raman spectroscopy is a type of vibrational spectroscopy. These similar methods have some differing qualities, as IR bands emerge due to alterations in the dipole ...

Researchers have measured hundreds of individual quantum energy levels in the buckyball, a spherical cage of 60 carbon atoms. It's the largest molecule that has ever been analyzed at this level of ...
