Default Continuously Tunable 250 GHz Gyrotron with a Double Disk Window for DNP-NMR Spectroscopy

From The DNP-NMR Blog:

Continuously Tunable 250 GHz Gyrotron with a Double Disk Window for DNP-NMR Spectroscopy

Jawla, S., et al., Continuously Tunable 250 GHz Gyrotron with a Double Disk Window for DNP-NMR Spectroscopy. J Infrared Milli Terahz Waves, 2013. 34(1): p. 42-52.


http://dx.doi.org/10.1007/s10762-012-9947-1


In this paper, we describe the design and experimental results from the rebuild of a 250 GHz gyrotron used for Dynamic Nuclear Polarization enhanced Nuclear Magnetic Resonance spectroscopy on a 380 MHz spectrometer. Tuning bandwidth of approximately 2 GHz is easily achieved at a fixed magnetic field of 9.24 T and a beam current of 95 mA producing an average output power of >10 W over the entire tuning band. This tube incorporates a double disk output sapphire window in order to maximize the transmission at 250.58 GHz. DNP Signal enhancement of >125 is achieved on a 13C-Urea sample using this gyrotron.

αH(i,i+1) NOEs in helical peptide, can this be present continuously...
Hi, I have observed some interesting NOEs for my peptide (5 kDa) in my 2D NOESY spectrum recorded at 900 MHz. I see NOEs that forms an α-helical pattern between 12-24 residues and N&C-terminus of my peptide is unstructured and does not have any secondary structure. The interesting part is, apart from seeing helical NOE patterns, such as αN(i,i+3)and αβ(i,i+3) for the residues between 12 & 24, I see in the alpha proton chemical shift regions of my 2D NOESY spectrum, a continuous αH(i,i+1) NOEs for the residues where I have helical secondary structural region (12-24 aa). That is, I see NOE...

[Question from NMRWiki Q&A forum] edasp window for 1H/19F double resonance experiment
edasp window for 1H/19F double resonance experiment Hello to all, This time I am having problem with doing a double resonance experiment. The final goal is to do 1H/19F-HOESY, but I am confused in the edasp window:http://dl.dropbox.com/u/12535433/04.JPG I remember I was doing 1H/13C heteronuclear shift correlation experiments before. I think for 13C it uses X-transmitter(!) and x100W amplifier. A normal 1D-19F works fine (H50W-X-XBB).It is a NMR300 and a QNP probe.Thanks is advance,Amin Check if somebody has answered this question on NMRWiki QA forum

Tunable paramagnetic relaxation enhancements by [Gd(DPA)3]3‚?? for protein structure
Abstract Paramagnetic relaxation enhancements (PRE) present a powerful source of structural information in nuclear magnetic resonance (NMR) studies of proteins and protein‚??ligand complexes. In contrast to conventional PRE reagents that are covalently attached to the protein, the complex between gadolinium and three dipicolinic acid (DPA) molecules, 3‚??, can bind to proteins in a non-covalent yet site-specific manner. This offers straightforward access to PREs that can be scaled by using different ratios of 3‚?? to protein, allowing quantitative distance measurements for nuclear spins...
