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.

The protein haemerythrin (Her) is responsible for binding and carrying O2 in some invertebrates. Each protein molecule has two Fe2+ ions that are in very close proximity and work together to bind one molecule of O2, form ing an Fe2O2 group. (a) The Raman spectrum of oxygenated haemerythrinobtained with laser excitation at 500 nm has a band at 844 cm-1 which has been attributed to the O-O stretching mode of bound 16O2. Why is Raman spectroscopy and not infrared spectroscopy the method of choice for the study of the binding of O2 to haemerythrin? (b) Proof that the 844 cm-1band in the Raman spectrum of oxygenated haemerythrin arises from a bound O2 species may be obtained by conducting experiments on samples of haemerythrin that have been mixed with 18O2, instead of 16O2 . Predict the fundamental vibrational wavenumber of the 18O-18O stretching mode in a sample of haemerythrin that has been treated with 18O2.

Potassium dichromate and potassium permanganate have overlapping absorptionspectra in 1M H2SO4 . K2Cr2O7 has an absorption maxima at 440 nm, and KMnO 4 has a band at 545nm (the maximum is actually at 525 nm, but the longer wavelength is generally used whereinterference from K2C2O7 is less). A mixture is analyzed by measuring the absorbance at these twowavelengths with the following results: A 440 =0.405, A 545 =0.712 in a 1-cm cell. The absorbances ofpure solutions of K2Cr2O7 (1x10 -3 M) and KMnO 4 (2.00x10 -4 M) in 1 M H 2 SO 4 , using the same cell gavethe following results: A Cr,440 = 0.374, A Cr,545 = 0.009, A Mn,440 =0.019, A Mn,545 = 0.475.
