Please provide a structure consistent with the following IR, 13 C NMR, and 1 H NMR spectra. Assign at least 2 bands in the IR and assign ALL protons in the 1 H/ 13 C NMR spectrum

Rose bengal is a chromophore used in biological staining that has an absorption maximum at 559.1 nm and several other shorter wavelength absorption bands in the ultraviolet and visible regions of the spectrum when dissolved in ethanol. What is the energy difference, in kilojoules per mole, between the absorption maximum at 559.1 nm and a band at 221.5 nm? E = kJ/mol

Two fo the wavelengths emitted by a hydrogen atom are 102.6 nm and 1876 nm. Whare are the Balmer formula n and m values for each of these wavelengths?
