Sigma Aldrich Fine Chemicals Biosciences Acetone-d6 99.9 atom D50G
Acetone-d6 (CD3COCD3 Hexadeuteroacetone) is the hexadeuterated form of acetone in which all hydrogen atoms in acetone molecule have been replaced by deuterium (D) atoms. It is a standard purity solvent for NMR (Nuclear Magnetic Resonance) analyses. Absorption spectra of CD3COCD3 samples cooled in molecular jet (jet-cooled) have been evaluated in the range of 51000-54000cm-1. Collision of its molecular ions with a perdeuterated surface (C20D41 SAu) was investigated by ion-surface collision spectroscopy. The Infrared and Raman spectra of acetone-d6 have been analyzed. It undergoes H-2H exchange reaction with acetone d0 to afford acetone d1 and d5.
