Molecule Optical Polarisation Laboratory focuses on investigating the structure and interactions of electronic states in diatomic molecules, specifically in order to optimise methods and to develop solutions for efficient laser synthesis of ultra-cold diatomic ensembles in their lowest rovibronic states. Experiments are based on high resolution (below 0.01 cm-1) Fourier-Transform spectroscopy combined with laser-induced fluorescence; deperturbation treatment and ab initio calculations are applied for obtaining high accuracy experiment-based potentials and interaction parameters. Additionally, a Bruker IFS 125 Fourier-Transform Spectrometer, with resolved linewidths from 0.006 cm-1 to 0.05 cm-1 over the spectral range from 750 cm-1 to 50,000 cm-1 (200 to 13300 nm), respectively, in conjunction with a multi-pass absorption cell offers possibilities to determine the low concentration of small molecules.
