You are considering purchasing a new NMR instrument so that you can do H1 NMR. Suppose one instrument would provide a magnetic field of 10T and another would provide a field of 3T. 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 itnernal magnetic field of the molecule.

I need help with 4 (  not a graded question, its for a lab homework)

Which of the following statements concerning spectroscopy is correct? A) Concentration of a solution is directly proportional to the % of photons transmitted. B) Salt plates are often used in IR spectroscopic measurements because they are transparent in that region. C) Molar absorptivity is a constant for given species, regardless of concentration or wavelength. D) Fluorescence excitation is usually red-shifted from emission wavelength. E) 2 or more statements are correct. The absorbed energy to enable vibrational level transition falls within which wavelength range A) radio wave B) microwave C) IR D) X-ray E) UV and visible

What is the wavelength (in cm) of the waves emitted by an NMR spectrometer that operates at a radio frequency of 700 MHz?

Cyclohexene and 2 hexyne both have the molecular formula C6H10. How would you use infrared spectroscopy to distinguish between these two compounds?

place the following nuclei in descending order of reference frequency for the same instrument. P31, N14, N15, F19, H1, Si29, H2, C13

5. Calculate wavenumber for C=C and C=C by Hook's law. stronger bond higher frequency f force constant v =k/m Hooke's law M=mass k = constant smaller mass -higher frequency The force constant (f) of C=C 10 x 105 dyne/cm and C=C, 15 x 105 dyne/cm The mass (m) is the mass of atoms (or weights). The smaller the value of m, the higher the V of vibration. CH3O. H. HO capsaicin (spicy component of hot peppers)

3. A solution of [FeSCN]2 is found to have 37.4 % transmission at 447 nm. If the molar absorption coefficient (e) is 4400 at Amax 447 nm, what is the concentration of [FeSCN]2 in the solution?

how can i get value of I( nuclear spin number)? in some question proton has 1/2=I value  and 11B is I=3/2 how did they got the value of I from 1H and 11B?

A molecule absorbs radiation of frequency 3.00x1014 Hz. What is the energy difference between the molecular energy states involved?
