【Abstract】 The application of frequency modulation and magnetic rotation techniques to the velocity modulation spectroscopy is presented for detection of molecular ions. This technique not only keeps the advantage of successfully suppressing absorption signal from neutral molecules, but also possesses the feature of reducing the background noise to the quantum noise limit.更多还原
