In summary, we observed two decay components for the 7H tautomer of 2,6-dAP. We recorded an ultraslow component for all peaks. In addition, we recorded a faster component with the time constants equal to 25 ns for the origin and +214 cm -1 peaks. That component then becomes shorter with increasing pump energy, of the order of 1 -10 ns for the peaks at +511 and +984 cm -1 and 1429 ps at +1307 cm -1 with respect to the origin transition. shows the 2C-R2PI spectrum of the 9H tautomer from 34800 to 35650 cm -1 acquired with ionization at 213 nm. We assign the band at 34885 cm -1 to the origin transition of the 9H tautomer in agreement with our previous work. This origin transition is higher in energy by ~2500 cm -1 than the origin transition of the 7H tautomer. With increasing energy lifetimes shorten. Beyond ~500 cm -1 excess energy lines broaden, and decrease in intensity, suggesting a further decrease of the excited state lifetime. The lifetime in the picosecond regime quickly decreases by an order of magnitude beyond +180 cm -1 , and then by another order of magnitude beyond +700 cm -1 , relative to the origin transition. Fig. shows pump-probe traces for the origin and and for the +790 cm -1 peak. All pump-probe traces and their fits are presented in Fig. . Figure . 2C-R2PI spectrum of the 9H tautomer of 2,6-diaminopurine in the gas phase using the ps 213 nm as probe. The origin transition is assigned to 34885 cm -1 . Lifetimes are displayed above the corresponding peaks, in ps. The lifetime of 6300 ps was measured in the ns regime using the 193 nm probe and matches previously published measurements. Lifetimes were measured at the origin, 34885 cm -1 , and +73, +110, +183, +239, +790 cm -1 , relative to the origin.
