- Answer the questions regarding a single Fourier transform infrared spectroscopy (FTIR) experiment. The interferogram was sampled at a retardation interval (8) of 0.0001297 cm. What wavenumber range is possible with a sample retardation interval (8) of 0.0001297 cm? Aỹ = cm- For a spectrum acquired in 8-bit space (256 data points sampled) for ô = -A to d = +A , determine the value of maximum retardation (A) and the resolution (R). A = cm R = cm-1 What is the interferometer mirror velocity if each data point required 267 us (tintt) to obtain? Vint = cm/sarrow_forward(b) An aqueous solution whose concentration is 0.00344 M was analysed using spectrophotometer with a molar absorptivity of 412 cm-1 mo1 L in a cell with a 2.00 cm pathlength. Calculate the absorbance and transmittance for the above solution.arrow_forwardExplain why an internal standard is required during sample preparation in quantitative analysis when using atomic spectroscopy?arrow_forward
- Assuming an integrated luminosity of 100 fb is collected at the ATLAS detector at the LHC, calculate the number of h ZZ events where both Z bosons decay to either a ete pair or a u u palr. You may assume that the total Higgs (h) production cross section is o, = 2 x 10' fb, the branching fraction for a Z boson decay to a ee pair is 3.36%, the branching fraction for a Z boson decay to a "u pair is 3.36%, and the branching fraction for a Higgs boson to decay to a pair of Z bosons is 2.7%. Enter your answer in the box below rounded to the nearest integer (e.g. 1234.4 should be entered as 1234). Ancwerarrow_forward(a) What is the main difference between a UV-Vis spectrophotometer and a spectrofluorometer? (b) What is the main advantage of using a spectrofluorometer in quantitative analysis?arrow_forwardA Raman spectrum of undoped GaAs at room temperature is performed with a 514.5 nm laser. The spectrum of scattered light exhibits peaks at wavelengths of 507.1 nm and 591.6 nm due to interaction of the incident light with LO phonons. Calculate the LO phonon frequency and the ratio of the intensity of scattered light at 507.1 nm to that at 591.6 nm.arrow_forward
