Understanding molecular state evolution is central to many disciplines, including dynamics, precision measurement, and molecule-based quantum technology. Details of the are obscured when observing a statistical ensemble molecules. Here, we reported real-time observations thermal radiation-driven transitions between individual states ("jumps") single molecule. We reversed these "jumps" through microwave-driven transitions, resulting in twentyfold improvement time molecule dwells chosen state. The measured transition rates showed anisotropy environment, pointing possibility using molecules as in-situ probes for strengths ambient fields. Our approaches detection manipulation could apply wide range species, facilitating their uses fields science, physics, ion-neutral chemistry.
