- What is the difference between continuous and discrete spectra?arrow_forwardThe following are sets of rotational quantum numbers (J,MJ,K). Label each indicated transition as either allowed or forbidden. Hint: Remember the rules for allowed values of the various quatum numbers. a (0,0,0)(1,1,0)b (0,0,0)(1,0,0) c (3,2,1)(3,1,1)d (4,4,1)(2,4,1)arrow_forwardThe following are sets of rotational quantum numbers (J,MJ,K). Label each indicated transition as either allowed or forbidden. Hint: Remember the rules for allowed values of the various quantum numbers. a (5,4,0)(3,6,0)b (8,2,2)(9,2,2) c (7,4,2)(7,4,2)d (4,2,5)(3,2,5)arrow_forward
- What is a rotating frame of reference?arrow_forwardWhat is the physical explanation of the difference between a particle having the 3-D rotational wavefunction 3,2 and an identical particle having the wavefunction 3,2?arrow_forwardConsider the following transitions 1. n=3 to n=1 2. n=2 to n=33. n=4 to n=34. n=3 to n=5(a) For which of the transitions is energy absorbed? (b) For which of the transitions is energy emitted? (c) Which transitions involve the ground state? (d) Which transition absorbs the most energy?

- Explain why X-ray lasers would be extremely difficult to build.arrow_forwardThe Chemistry and Life box in Section 6.7 described the techniquescalled NMR and MRI. (a) Instruments for obtainingMRI data are typically labeled with a frequency, such as 600MHz. In what region of the electromagnetic spectrum doesa photon with this frequency belong? (b) What is the valueof ΔE in Figure 6.27 that would correspond to the absorptionof a photon of radiation with frequency 450 MHz? (c) Whenthe 450-MHz photon is absorbed, does it change the spin ofthe electron or the proton on a hydrogen atom?arrow_forwardUse the Tanabe-Sugano diagram to indicate the electronic transitions for the configurations below, i.e. for example, 'A2 →³T2 is one transition for ³F. (a) d³ (b) dºarrow_forward
- Single atoms only undergo electronic transitions. True Falsearrow_forward(a) What energy photons can pump chromium atoms in a ruby laser from the ground state to its second and third excited states? (b) What are the wavelengths of these photons? Verify that they are in the visible part ofthe spectrum.arrow_forwardAtomic absorption spectrophotometry is a method for the quantitative determination of metal ions. a) Describe in detail the AAS instrument and especially the parts that differ from a normal spectrophotometer. b) What light source is used in this technology and how does it work? c) What interferences can occur with this equipment? d) What is the theoretical basis of the AAS method?arrow_forward
