Abstract
The design of a chirped-pulse Fourier transform microwave spectrometer CP-FTMW combined with a laser ablation LA source is presented. The spectrometer is capable of measuring the 6.5-18 GHz region. Rotational spectra of solid samples of proline (m.p. 228 $^irc$ C) and alanine (m.p. 290 $^irc$ C) vaporized by laser ablation has been recorded. Four low-energy conformers of proline and two in alanine have been detected. $^{13}$C species of alanine in their natural abundance have been also observed. The performance of this spectrometer is compared to a LA-MB-FTMW spectrometer.
