Nuclear Magnetic Resonance

Nuclear magnetic resonance is probably the most important analytical method for any chemist working synthetically. High-resolution NMR of liquids and solutions is performed in close cooperation with the Institute of Chemistry, University of Rostock. Alongside with the commonly regarded qualitative application of NMR (structure elucidation), this technique has a very strong potential for quantitative determination and investigation in molecular dynamics.

Information on the regular service and on the available software you will find on our intranet pages.

This is our equipment:

AV-III HD 400 (Bruker)

(last hardware update 2017, magnetic flux 9.4 Tesla, proton resonance frequency 400 MHz). This instrument is equipped with four independent frequency channels and is used in the main for solving special problems, such as 2D NMR, hetero (X) nuclei including transition metals, variable temperature work) with the following probe:

• BB (5 mm), triple resonance ¹H, ¹⁹F and BB ³¹P-¹⁵N; z gradient

Further probes may serve to perform special tasks:

• BB (10 mm), frequency range ³¹P-¹⁰³Rh
• BB (5 mm, inverse), triple resonance ¹H, ³¹P and BB ³¹P-¹⁰³Rh
• BB (5 mm, inverse), frequency range ³¹P-¹⁵N; z gradient
• BB (5 mm), frequency range ³¹P-⁹⁷Mo; z gradient
• QNP (5 mm), ¹H/¹³C/²⁹Si/³¹P
