Please, if somebody wants to help me?! I need to get 1H spectrum with spin lock pulse on Bruker AV 600 instrument. Which pulse sequence and which parameters should be used, please? Thank you, thank you, Marijana from Croatia

Internal motions in the microsecond timescale have been proposed to play an active part in a protein’s biological function. Nuclear magnetic resonance (NMR) relaxation dispersion is a robust method sensitive to this timescale with atomic resolution. However, due to technical...
ROESY spin-lock power
I'm using roesyph.2 pulse sequence and I would like to know how to calculate spin-lock power in Hz for this experment.
Thnx

ps. I'm aware that for hard pulse it is 1/pw360, therefore can I assume that in this case it is 1/2*P25?

Authors: Korzhnev DM, Skrynnikov NR, Millet O, Torchia DA, Kay LE
Rotating-frame relaxation rates, R(1)(rho), are often measured in NMR studies of protein dynamics. We show here that large systematic errors can be introduced into measured values of heteronuclear R(1)(rho) rates using schemes which are...
