text: Albrecht is most well known for his work on the theory of resonance Raman scattering intensities. He developed two of the main methods for analyzing Raman enhancement patterns. The first of these is the sum-over-states method, developed in the 1960s. After the development of the competing time-dependent wavepacket method by Lee and Heller, Albrecht's group developed the transform theory of resonance Raman enhancement.
  Other notable research developments by his group research include thermal lensing spectroscopy, and the concept of local molecular vibrational modes.
