The magnetic circular dichroism (MCD), induced circular dichroism (ICD) spectra, and the absorption spectra of N-bromophthalimide have been measured. The ICD spectrum of the b-cyclodextrin complex with Nbromophthalimide is also reported. The absorption bands of N-bromophthalimide are assigned. Intr
