What features of FTIR spectroscopy make it useful for applications in sorting plastic recycling? Are there any disadvantages? Briefly explain.

In IR spectroscopy, please shortly explain what is a sample? Please answer at your own words.

Which of the following light sources can be used to examine a fluorescent dye that absorbs at 440 nm in molecular spectroscopy? I. xenon arc lamp II. deuterium lamp III. tungsten lamp IV. hollow cathode tube

7 of 10 > Atomic absorption spectroscopy was used to determine the amount of aluminum in a sample of sunscreen. A blank solution was measured seven times to determine the detection and quantitation limits of the spectrometer. The blank readings were: 0.0073, 0.0082, 0.0110, 0.0101, 0.0102, 0.0098, and 0.0090 AU. Determine the signal at the detection limit and the signal at the limit of quantitation for this method. signal detection limit: signal limit of quantitation: hulu étv 14

When is 2D NMR usually used and why?

Spectroscopic Analysis https://www.youtube.com/watch?v=ZfMPyZiDsf4&list=PLE-217H0ao60Uzpzj-FNP_0ScVp5SZB7j&index=2 watch the following question and read the article to answer the questions Spectroscopic Analysis-1 a.Which of the following statements regarding IR spectroscopy is wrong?     Infrared radiation is higher in energy than UV radiation.     Infrared spectra record the transmission of IR radiation.     Molecular vibrations are due to periodic motions of atoms in molecules, and include bond stretching, torsional changes, and bond angle changes.     Infrared spectra give information about bonding features and functional groups in molecules.   b.Which is the correct order of decreasing wave number of the stretching vibrations of (1) C-H (alkane), (2) C-H (alkene), (3) C-H (alkyne), and (4) C=O?     (1) > (2) >(3) >(4)     (4) < (3) < (2) < (1)     (3) < (4) ≈ (2) < (1)     (1) < (4)…

A student calibrated the mini-spectrophotometer with a blank solution, and then went to check their solution. They got a fingerprint on the cuvette while filling it. Because of this, the expected reading for the absorbance would be too high which would cause the calculated value of K, to be too high
