For each spectrum, draw the compound and designate which peaks coordinate to which features on your compound. Include the spectra with your report. How might the aspirin spectra appear if it was not completely purified (ie. if there was left over salicylic acid)?

sorry i cant provide IR
but you can get in google image
i am providing here only H1 NMR and 13C NMR
first two spectra are for the salicylic acid
second two spectra are for the Asprin

for the following 2 compounds, please calculate, and
show the calculations for, the degree of unsaturation, assign the
IR spectrum peaks, assign the 13C NMR peaks, assign the 1H NMR
peaks, and draw the structure for the unknown compound.
CHIM 245 Spectroscopy Problem Set #2 In this problem set there are two unknown compounds. You are provided with the formula, IR spectrum, "C NMR spectrum, and 'H NMR spectrum for each compound. Each unknown is worth 10 points, with an...
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 showing a "zoom-in" on an important...

Spectroscopy of C5H10O
1. Correctly label 2 peaks in the IR spectrum with the appropriate functional group. 2. Correctly label 1 peak in the 13C NMR spectrum. 3. Draw some possible structures (isomers) as you analyze the 'H NMR spectrum. 4. Draw your final choice of structure to match the IR. 13C NMR, and H NMR 5. Label the different types of hydrogens on your structure as a, b, c, etc. Label the peaks in the 'H NMR spectrum with...

The mass spectrum of compound A shows molecular ion peak at m/z 88. The IR spectrum of this compound has a broad peak between 3200 and 3550 cm-1. The 1H NMR spectrum of A shows the following peaks: a triplet at d 0.9, a singlet at d 1.1, one more singlet at d 1.15, and a quartet at d 1.6. The area ratio of these peaks is 3:6:1:2. The 13C NMR contains 4 signals. In the space below, propose a...
Draw the structure of the compound C_9H_10O that exhibits the^13C-NMR spectrum below. Impurity peaks are omitted from the peak list. The triplet at 77 ppm is CDCl_3. Used with permission from Aldrich Chemical Co., Inc. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Do not include lone pairs in your answer. They will not be considered in the grading.
