The Arndt-Group has a new paper on "Selective photodissociation of tailored molecular tags as a tool for quantum optics" in the Beilstein Journal of Nanotechnology!

Recent progress in synthetic chemistry and molecular quantum optics has enabled demonstrations of the quantum mechanical wave–particle duality for complex particles, with masses exceeding 10 kDa. Future experiments with even larger objects will require new optical preparation and manipulation methods that shall profit from the possibility to cleave a well-defined molecular tag from a larger parent molecule. Here we present the design and synthesis of two model compounds as well as evidence for the photoinduced beam depletion in high vacuum in one case.

Figure 4: Molecular beam machine to study the photodepletion of the photoactive monomer in high vacuum. The pulsed infrared laser beam desorbs the molecules which are entrained by the adiabatically expanding neon gas jet. The neutral beam propagates for 75 cm in high vacuum before it is ionized by the pulsed radiation of a 157.6 nm F2 laser and analysed in a time-of-flight mass spectrometer. On the way to the detector the molecularbeam is exposed to a collinear UV laser beam at 266 nm.
