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.
