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 ...

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 ...

In the new method using quantum systems, the team converted low-energy MIR photons into high-energy visible photons using molecular emitters. The innovation has the capability to help scientists ...

Due to its enormous 60-atom size, the overall molecule has a staggeringly high number of ways to vibrate--at least 100,000,000,000,000,000,000,000,000 vibrational quantum states when the molecule ...
