We are pulsing the light to allow the kinetics of the polymerization to occur
On our NEo 500 we observe about a 1 degree increase in temperature which
returns to baseline within a few minutes
Hope it helps

Hi all,
I've noticed that some photochemistry setups are designed so that the light
is on for only part of the pulse sequence (and controlled by an output from
the NMR console) whereas other setups have the light on all the time. Under
what experimental conditions is it necessary to turn the light off for part
of the pulse sequence? For example, if we are using light to convert an azo
dye from the trans- to cis- conformation and then observing the changes in
the proton spectrum (or in a NOESY), is it OK to have the light on the whole
time?
Thanks!
Wendy
