A titrimetric method for the microdetermination of indole and its derivatives withN-bromoacetamide is described. It has been observed thatN-bromoacetamide brominates the compound containing indole nucleus in the presence of acetic acid. The usual rea

The position and intensity of the absorption bands of a number of chalcone dyes have been calculated on the basis of the free-electron molecular-orbital (FEMO) theory. The three to four absorption maxima of the chalcones are calculated by assuming th
