Observation of Carbonic Acid Formation from Interaction between Carbon Dioxide and Ice by Using In Situ Modulation Excitation IR Spectroscopy
Abstract Carbonic acid, H 2 CO 3 , is of fundamental importance in nature both in living and non‐living systems. Providing direct spectroscopic evidence for carbonic acid formation is however a challenge. Here we provide clear evidence by in situ attenuated total reflection IR spectroscopy combined...

Abstract Carbonic acid, H 2 CO 3 , is of fundamental importance in nature both in living and non‐living systems.
