DESCRIPTION: Time-resolved infrared spectroscopy (TRIR) is a powerful tech
 nique for studying ultrafast molecular dynamics and material properties. I
 t provides critical insights into chemical processes like DNA structure fo
 rmation and reactions relevant to drug development. This thesis establishe
 s a time resolved transient absorption spectroscopy setup at the Laborator
 y of Intense Laser (L2I)\, under the Group of Lasers and Plasmas (GoLP) at
  the Instituto de Fusão Nuclear (IPFN). Our lab features a high-energy 3 
 μm laser system with 6.5 W average power\, 40 fs pulse duration\, and 100
  kHz repetition rate\, as well as a 1.030 μm system capable of achieving 
 100 fs pulses. By leveraging these ultrafast laser systems\, we can monito
 r sub-picosecond transient states of molecules\, advancing our understandi
 ng of fast molecular interactions. Initial testing was conducted using rho
 damine 6G as a model system\, with the 1.030 μm laser as the pump and 515
  nm probe. The results demonstrate the potential of our setup for time-res
 olved studies. With these unique resources\, our laboratory is positioned 
 to make significant contributions to the field of ultrafast TRIR spectrosc
 opy\, which has applications ranging from basic scientific research to ind
 ustrial innovation. This work sets the stage for exploring dynamic process
 es at the molecular level\, providing valuable data for fields such as mat
 erials science and biochemistry.
