The experimental configuration of the pump-probe experiment is similar to Ref. [5]. A home built non-collinear optical parametric amplifier (nc-OPA) was used as a pump, providing Fourier-transform-limited 30 fs pulses, which could be spectrally tuned between 480-560 nm. In all experiments white-light generated in a sapphire crystal using part of the fundamental laser (800 nm), was used as probe light. In the pump-probe experiments the pump was tuned to the S2 0-0 band for carotenoids with n>l 1. In the case of M9, it was not possible to tune the nc-OPA to its 0-0 transition, and hence another nc-OPA tuned to 900 nm was frequency doubled and used for excitation. In addition to conventional transient absorption pump-probe measurements, we introduce pump-deplete-probe spectroscopy, which is sensitive to the function of an absorbing state within the deactivation network. In this technique, we...

To analyze the spectral tuning of dCRNs, food extracts or mixtures of chemicals mimicking such extracts have been used as search stimuli and this limits our knowledge about stimulatory chemicals for crustacean dCRNs to mainly food-related substances. The chemicals most widely tested and found to be stimulatory are L-amino acids followed by ammonium chloride, betaine, nucleotides, amines, sugars, pyridines, organic acids, and small peptides. Only rarely, other chemicals, including the putative pheromone ecdysone (Spencer and Case 1984), were tested...
