WIRMS 2019 will be held in Brazil, and promoted by the Brazilian Synchrotron Light Laboratory (LNLS/CNPEM), from the September 23rd to 28th , 2019. The workshop will highlight the latest advances in infrared spectroscopy and imaging inside synchrotron and free electron laser facilities. The event will gather around 100 participants including infrared spectroscopy experts in several modalities such as ultra-resolved chemical imaging, vibrational analysis at extreme environments, THz spectroscopy, new infrared sources and detectors, time-resolved chemical analysis, infrared spectral-tomography among others.
