Nuclear Magnetic Resonance (NMR)

The Nuclear Magnetic Resonance Bruker Avance III HD 400(NMR) facility at Shiv Nadar University is equipped with a 400-MHz magnet (operating field at 9.4 Tesla), a multinuclear broadband probe (one NMR probe) covering NMR active nuclei (H, C, P, N, F, Si, Hg, Pt) and temperature controllable probe head (±150 °C). This instrument is useful for regular sample characterization and quantitative analysis of mixtures containing known compounds. Further, it can be used to study various physical properties at the molecular level, such as molecular conformation, conformational exchange, and diffusion, by utilizing multidimensional (2D) NMR.
