What is the Structure?
Information: Each spectra below was obtained from a pure compound. Mass Spectrum parent peaks (M) are listed for all examples. IR peaks listed are strong (s) unless otherwise indicated for signals above 1500 cm 'H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given...

Spectroscopy 1. What is the relationship between the infrared spectrum and the molecular structure in the structural determination of organic compounds by means of the correlation tables? 2. How does the interaction between the UV-Vis radiation energy and the material occur? 3. How are electronic removals carried out according to their different types of transition? 4. Indicate the absorption maxima of the most common chromophores and the factors that determine their displacements: the conjugation and the solvent. 5. How is...

Please help me determine the structure from the data below. I
know there are 10 total hydrogens. However, I am unsure of how many
oxygen would be in the structure. There are 2 peaks of 1668 and
1662 that I think are C=O but I am not sure.
