Question

Aqueous solution of mesityl oxide show two absorption peaks at Lamda Max 305 and 243 nm in its UV spectrum identify the electronic transition for them

Answer 1

Answer:

Complex 1 is [Cu(ip)2H2O](ClO4)2

Complex 2 is [Cu(dppz)2H2O](ClO4)2

Based on absorption spectral techniques i have studied binding ability of these complexes with DNA. A reviewer has raised a question as why complex one shows two absorption peak and complex 2 shows one peak.
