Given the background IR spectra, rank the three methods (Nujol mull, CCl4 solution, and KBr pellet) in order of best to worst spectra collected on a solid sample and explain your ranking.
Provide a brief justification for the identification of 1-propanol, hexane, benzyl alcohol, 1-hexanol and ethyl benzoate based on 2-3 key bands in each spectrum, which suggest the presence (or absence) of specific functional groups. You do not need to identify all the bands in the spectra -that would be almost impossible. If the bands are too similar (or in addition, to strengthen your discussion), you could look the IR spectra of the compounds in a database and see whether the IR of the unknowns can be identified this way.
Absorption bands in the region of 1600-1700 cm-1 are often used for quantification of caffeine. What does the bands in this region refer to?

How do I solve for [FeSCN2+] heres the formula they provided me and my data but I would like steps on how to solve it and what data I should be using to solve for it u can use any fake numbers you need to help me understand ! I'm confused only by the absorbance part , what number am I using for the absorbance? Is it Fe3+ added to ScN- absorbance values ? also e = 202 and L = 1.0
What is the structure of the unknown? Determine it by analyzing the spectroscopic data given in IR, MS, 1H NMR, 13C NMR (Broadband decoupled with carbon types) and fully substantiate your answer with key supporting data from each spectrum.
1. True or False a. UV-Vis spectroscopy normally reports data in the from of bands rather than single peaks because of overlapping electronic transitions that are being recorded by the detector. (T/F) b. When using linear regression to translate absorption data using Beer's Law, the y-intercept (+b) of the linear equation represents the path length. (T/F) c. Phosphorescent materials give a glowing effect because the electrons remain at an excited state for much longer, which is the cause for the "glow". (T/F)
