NMR Probes and Experiments
QNP: 1H, 13C, 19F, 31P. Virtually any experiment involving these nuclei can be run with this probe installed. Nuclei other than 13C and 31P on the broadband channel cannot be run (e.g. 11B, 77Se).
Cryoprobe: 1H/13C/15N inverse probe, similar to the TXI (below) in that 1H is directly detected. The probe is very sensitive for 1H detection, the 1H electronics are cooled to 11 K to reduce thermal noise. Detection of 1H is about 5 times that for a conventional probe. This probe was not designed to directly observe 13C or 15N, and it is recommended that another probe be used if you wish to observe either nucleus directly.
H/F: 1H and 19F only.
BBO: Best for 13C and 31P experiments. Any other X-nucleus (e.g. 11B) can be run with assistance from Dr. Dumais or Ms. Basiaga. 19F cannot be run on this probe. Inverse experiments (HMQC) and homonuclear experiments (COSY, NOESY) will have lower sensitivity.
BBI: Best for 1H, homonuclear experiments (COSY, NOESY), and inverse experiments (HMQC). 19F cannot be run on this probe. 13C and 31P will have lower sensitivity.
TXI: 1H/13C/15N inverse probe, 1H is drectly detected and 13C and 15N are indirect detection. Very good signal for 2D homonuclear and inverse experiments involving 13C or 15N. Other nuclei cannot be observed on this probe.
Flow Probe: Used for LC-NMR.
Solids: Solid samples. See Dr. Dumais if you want to arrange time to run a solid sample.
