Infrared absorption spectroscopy of a single polyatomic molecular ion.

Absorption spectroscopy is a fundamental tool for probing molecular structure 1 .

Absorption spectroscopy is a fundamental tool for probing molecular structure 1 . However, performing absorption spectroscopy on individual molecules is challenging because of the low signal-to-noise ratio 2,3 . Here we report on non-destructive absorption spectroscopy on a…
