Picometric Spectroscopy – Dynamics Of Hydrogen In Nanocavities

Ashok Lokhande
A remarkable advancement in picometric spectroscopy has allowed an international research team to achieve the single-molecule observation of hydrogen (H₂) and deuterium (D₂) molecules confined within incredibly small, atomically dimensioned volumes known as picocavities. This breakthrough utilizes advanced tip-enhanced Raman spectroscopy (TERS) to provide an unprecedented look into how molecules behave under extreme spatial confinement. The creation of these picocavities is a fascinating aspect.
