Deuterium Decoupling
Deuterium Decoupling
Bruker NMR spectrometers equipped with a 2H TX board and 2H amplifier can be setup to carry out 2H observation and decoupling experiments while still maintaining a 2H lock. Two channel systems can use the 2H transmitter for 2H, 1H[2H], 2H[1H] and X[2H] measurements. In addition to these, a three channel system can be set up for X[2H, 1H] measurements. The first figure below shows the 13C and 13C[2H] spectra collected for a mixture of deuterated solvents using two channels of an AVANCE spectrometer. The second figure shows the 13C, 13C[1H], 13C[2H] and 13C[1H, 2H] spectra for the standard 13C sensitivity sample (40% para-dioxane and 60% deuterobenzene) collected on a three channel Bruker AVANCE spectrometer.
