The researchers tested their method, which they term field-resolved infrared spectroscopy (FRS), on several biological samples. In measurements of human blood serum, they detected changes as small as ...

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, ...

The R branch ro-vibrational lines are shown on the left and the P branch ro-vibrational lines are shown on the right. Only the first few J levels are shown. Where h is Planck’s constant, ν is the ...

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 ...
