编辑部回信的意见如下，请教大虾这是什么意思呢？For the free compound, absorption bands are present at 325 and 425 nm. It is stated that fluorescence band appears at 390 when excited to 355. How can be the fluorescence band (at 390) shifted to the blue regarding an absorption band located to 425?. I think that an excitation spectra ad different emission wavelengths could shed light in this apparent inconsistency.
