Structural analysis using NMR (nuclear magnetic resonance) spectroscopy.
Measurement of the light solvent as is.
NMR is typically performed using the resonance signals of deuterium (2H or D) nuclei in deuterated solvents for reasons such as ensuring the stability of the magnetic field. However, by using the resonance signals of proton (1H) nuclei, measurements can also be conducted with light solvents (i.e., regular solvents) (No-D measurement method). The effective measurements for the No-D method are as follows: - Measurements to evaluate interactions with light solvents (e.g., degradation studies in light solvents) - Measurements of samples that cannot use deuterated solvents (e.g., samples in the biochemical field such as proteins) - Measurements of samples containing volatile components - Measurements of samples for which no dissolvable deuterated solvents are available.
