T h c magnetic circular dichroism spectra of a numbcr of indolc alkaloids show two B-tcrms of opposite sign in thc 250-330 nni wavelength region associated with the l L b and lL, clectronic transitions, thc long ivavelength, lLt,, band being of positive sign, whereas both bands strongly ovcrlap in a
## Sumnary: transition The unexpected observation of a pair of oppositely signed MCD bands within the Qi of monoacetyl porphyrins is related to the existence of equilibria between N-H proton tautomers and/or conformational populations of the acetyl substituent. Substituent-induced sign variation
