Hi Everyone,
I would like to get a consensus for how long people typically set their D1
delay to detect quaternary and/or carbonyl carbons. Our default at 500 MHz
is 1s for 13C and the quaternary/carbonyl carbons are often weak. I tell
students they have to increase the D1 delay but I give them vague answers
for exactly how long it should be, 5s, 10s, 30s, 1 min? Without measuring
the T1s I don't have an exact answer to give them and "trial and error"
tends to waste a lot of instrument time. Sorry if this seems trivial but I
would be interested in knowing what my colleagues recommend.
Thanks,
Mark Swanson
