FT IR Spectroscopy What is meant by rotating frame of reference? That the sample is spun rapidly in the applied field That the detector rotates around the sample None of these If the laboratory itself is imagined to be rotated at the Larmor frequency, viewing that individual magnetic moment vectors are fixed in space That the sample is spun rapidly in the applied field That the detector rotates around the sample None of these If the laboratory itself is imagined to be rotated at the Larmor frequency, viewing that individual magnetic moment vectors are fixed in space ANSWER DOWNLOAD EXAMIANS APP
FT IR Spectroscopy Why is it advantageous to record many FID signals from the same sample and then add them together?

FT IR Spectroscopy What does the Michelson interferometer do? Selectively filter certain wavelengths from a beam of I.R. radiation None of these Split a polychromatic beam of radiation into its component wavelengths Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector Selectively filter certain wavelengths from a beam of I.R. radiation None of these Split a polychromatic beam of radiation into its component wavelengths Modulate the I.R. signal at a lower frequency, so that it can be observed by a detector ANSWER DOWNLOAD EXAMIANS APP
