Ps 2 absorption maxima
WebbThe invention relates to the molecule containing a first chromophore that exhibits a first absorption maximum above 700 nm and a second chromophore that exhibits a second absorption maximum different from the first absorption maximum, wherein the absorption of the first and second chromophores are substantially independent of each other. 例文 … WebbThe absorption is highest at around 510 nm (the wavelength at which absorption reaches its peak is called absorption maximum wavelength). This tells us that the iron solution …
