Talk:Nitrocefin

Spectrum
"Hydrolysis of nitrocefin however, produces a shift of ultraviolet absorption inside the visible light spectrum from intact (yellow) nitrocefin (~380 nm) to degraded (red) nitrocefin (~500 nm)" sounds not quite right in a couple of ways. First, that's not ultraviolet absorption; second, 380nm isn't yellow and 500nm isn't red.

I think what the linked reference says is that (a) cephalosporins usually have an ultraviolet absorption peak, (b) this compound also has a purple (~380nm) absorption peak, making the compound yellow, and (c) on hydrolysis the absorption peak shifts to 500nm (green), making the compound red.
