Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

**Isoamyl Acetate NMR Analysis**

*Task*: Match the peaks in the NMR spectrum to the appropriate atom numbers in the isoamyl acetate structure. Note that a letter may correspond to more than one number.

**Chemical Structure Labels**:
- a
- b
- c
- d
- e
- f

**NMR Spectrum Description**:
- The spectrum spans from 0 to 3.5 ppm.
- Notable peaks:
- At 3.5 ppm: Peak labeled as `H` indicating a singlet with integration for 3 hydrogens (3H).
- At 2.7 ppm: Peak indicating 2 hydrogens (2H).
- Around 1.7 ppm: A multiplet for 1 hydrogen (1H).
- Between 0.9 ppm and 1.2 ppm: Peaks for 2 hydrogens (2H) and 6 hydrogens (6H), indicating triplets and/or quartets.

**Matching Structure and Peaks**:
- 3.5 ppm peak matches to atom *a*.
- 2.7 ppm peak matches to atom *e*.
- 1.7 ppm matches to atom *d*.
- Peaks around 0.9 and 1.2 ppm match to atoms *f* and *c*.
- The smallest peak around 0.8 ppm corresponds to atom *b*.

**Assignments**:
- 3 - a
- 3 - d
- 2 - e
- 4 - f
- 4 - c
- 1 - b

Ensure that when analyzing the NMR spectrum, each peak corresponds to a structural element in the compound, illustrating the hydrogen environments present in isoamyl acetate.
