(a) (b) The quantum yield of fluorescence for anthracene is seen to be higher than that of biphenyl. Draw the two compounds and explain why this is so. The UV spectrum of isoquinoline has four à max values at 318, 305, 266 and 218 nm. Draw the compound and suggest what you would expect to happen if acid was added to solution and the spectrum is retaken.
