Abstract in another language
It has been demonstrated recently that it is possible to observe the magnetic-resonance signal of a single molecular spin. This achievement represents the ultimate sensitivity in electron-spin resonance spectroscopy. In this contribution it will be explained how a single molecule in a molecular crystal can be selected using a cw, narrowband laser and how the magnetic-resonance transition in the photo-excited triplet state can be detected as a change in the fluorescence intensity. This experiment allows us to check whether or not the time-averaged signal of a single molecule is equal to the ensemble average, i.e. if the Ergodic Theorem applies. In experiments on molecules containing one 13C atom in natural abundance the presence of the single 13C nuclear spin (I= 1/2) is visible by the hyperfine splitting. This experiment opens the possibility to study the properties of a tingle nuclear spin.
