WebSep 5, 2024 · Deuterated Solvent Effects. One of the other aspects to solution-phase IR is that the solvent utilized in the cell has a characteristic absorption spectra. In some cases this can be alleviated by replacing the solvent with its deuterated sibling. The benefit here is that C-H bonds are now C-D bonds and have lower vibrational frequencies. Webanother is the cost of deuterated compounds. In order to resolve two issue, needs to improve production throughput and enehance reaction efficiency. Then, we have developed new synthesis technology for deuterated aromatic compounds using a flow synthesis method. This paper reports the developed synthesis method. 2.
