Hi, I'm meant to know this but I'm blanking, so I'll crowdsource instead:
Anybody know a (the) reference where it was showed that the best SAD data is obtained by collecting multiple revolutions at different crystal offsets (kappa settings)? It's axiomatic now (I hope!), but I remember seeing someone actually show this. I thought Sheldrick early tweens, but PubMed is not being useful.
(Oh dear, this will unleash references from the 60s, won't it.) phx
