FT IR Spectroscopy What is meant by rotating frame of reference? That the detector rotates around the sample If the laboratory itself is imagined to be rotated at the Larmor frequency, viewing that individual magnetic moment vectors are fixed in space None of these That the sample is spun rapidly in the applied field That the detector rotates around the sample If the laboratory itself is imagined to be rotated at the Larmor frequency, viewing that individual magnetic moment vectors are fixed in space None of these That the sample is spun rapidly in the applied field ANSWER DOWNLOAD EXAMIANS APP
