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 ...

IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

A team of Johns Hopkins engineers has developed a new, more powerful method to observe molecular vibrations, an advance that could have far-reaching implications for early disease detection. The team, ...

According to a study published in Nature Communications, researchers have created an extremely sensitive detector for identifying molecules based on their infrared vibrational “fingerprint.” ...

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 ...

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, ...

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 ...
