- Why does fluorescence tend to be the mirror image of absorption?What factors influence the wavelength of maximum emission and maximum excitation in fluorescence spectroscopy?Why high-resolution monochromator is needed for atomic emission spectroscopy while atomic absorption spectroscopy requires a monochromator having only low-to-moderate resolving power?
- The HNMR spectrum of acetic acid is shown below. Explain why the downfield singlet is much broader than the upfield singlet.Identify the mayor peaks and the vibrational modes of this infrared spectrum of a solid mixture between Acrylic Powder and KBr.The average bond enthalpies of the C—F and C—Cl bondsare 485 kJ/mol and 328 kJ/mol, respectively. (a) What isthe maximum wavelength that a photon can possess andstill have sufficient energy to break the C—F and C—Clbonds, respectively? (b) Given the fact that O2, N2, andO in the upper atmosphere absorb most of the light withwavelengths shorter than 240 nm, would you expect thephotodissociation of C—F bonds to be significant in thelower atmosphere?
- The region of the measured EMR in both molecular UV-vis absorption and fluorescence emission are the same. Name the radiation sources used in each instrument and explain the reasons for the different radiation sources used in the two instruments.-Explain The relation between the concentration and absorption based on beer's law in details.Use the data in Figure 4.8 to estimate the ratio of radiation intensity at 10,000 Å (infrared) to that at 5000 Å (visible) from a blackbody at 5000 K. How will this ratio change with increasing temperature? Explain how this change occurs.
- In Trans-[PdFCl] determine I'total, I'tran., Irot. and I'vib., Which mode(s) is (are) active in IR and Raman spectroscopy?Why it is not possible to obtain blue phosphorescence from a transition that initially absorbs blue light. Also suggest why phosphoresence spectra are sometimes better for identifying useful electronic transition for possible laser transition than are flourescence spectra.Explain why an internal standard is required during sample preparation in quantitative analysis when using atomic spectroscopy?
