When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region ...
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team ...
Vibrational microscopy methods offer bond-selective imaging, revealing the rich chemical composition of biological samples. In this Focus issue, we celebrate the past, present and future of these ...

Scientists in Germany have shed light on how nanoscale imaging techniques like tip-enhanced Raman spectroscopy (TERS) can be distorted by metal surfaces by creating a powerful method to simulate ...
Normal-mode analysis via Hessian diagonalization applied to ball-and-spring molecular models. Constructs Cartesian Hessians from bond-stretch and angle-bend force constants, mass-weights, diagonalizes ...
