a Ratio spectrum of binary mixture 240.0 μg/mL of PSE and 10.0 μg/mL of LOR using spectrum of normalized LOR′ as a divisor showing the value of constant at (277–326 nm). b The obtained ratio spectrum of binary mixture after subtraction of the constant value. c The obtained ratio spectrum of binary mixture after multiplication by recovery spectrum (normalized spectrum of LOR/normalized spectrum of PSE) showing the value of constant at 235–250 nm
