You are considering purchasing a new NMR instrument so that you can do 1H NMR. Suppose one instrument would provide a magnetic field of 10 T and another one would provide a field of 3 T. For a given molecule, would these two instruments have two different absorption wavelengths between spin states? If so, calculate the two different wavelengths that would cause absorption, ignoring the internal magnetic field of the molecule.

In 1H-NMR spectroscopy, signals are often distorted by the so-called “roof effects”. When do two signals influence each other so that you can detect the roof effect? How would two quartets be distorted if there were to be a roof effect between them? Please draw a sketch.

In Mass Spectrometry (MS) the molar mass of compounds can be determined. The so-called "molecular ion" corresponds to the molecular mass when Electron Impact Mass Spectrometry (EIMS, one of several common MS techniques) is used. It is important to realize, though, that the mass detected by MS depends on the isotopes present in the molecule. The questions below try illustrate the impact of isotope distribution in a molecule. What is the molar mass of the compound shown below? What is...

You are working on a project to make a more efficient engine. Your team is investigating the possibility of making electrically controlled valves that open and close the intake and exhaust openings for an internal combustion engine. This device is mounted on an axis so that it can spin freely to close the valve. Your assignment is to determine the stability of the valve by calculating the force on each of its sides and the net force on the valve....

Magnetic resonance imaging (MRI) is a medical technique for producing "pictures" of the interior of the body. The patient is placed within a strong magnetic field. One safety concern is what would happen to the positively and negatively charged particles in the body fluids if an equipment failure caused the magnetic field to be shut off suddenly. An induced emf could cause these particles to flow, producing an electric current within the...

An organic compound absorbs strongly in the IR at 1687 em. Its 'H NMR spectrum consists of two signals, a singlet at 2.1 ppm and a multiplet centered at 7.1 ppm. Its mass spectrum shows significant peaks at m/z 120, m/z 105 and m/z 77. This...

Can you type please if handwriting is not legible Imagine you work for a construction company that is considering a contract for a public sector highway project in another country. This country has battled excessive inflation in the past, but for the last 15 years inflation has been stable at around 7% to 10% per year. The highway project is expected to take two years to complete. The contract would bring in significant revenue to be paid annually in the...
