Conclusion

The new on-axis multimode spectrometer enhances the ability to study macromolecular structures and their radiation-induced changes.

Supporting Evidence

  • The spectrometer allows for the collection of both UV-Vis absorption and Raman spectra.
  • It provides complementary information to X-ray diffraction data.
  • The on-axis design reduces the need for time-consuming alignment procedures.
  • It enables the monitoring of radiation damage in protein crystals.

Takeaway

Scientists built a new tool that helps them see tiny details in proteins and other big molecules, even when they get damaged by light.

Methodology

The study involved the integration of a new spectrometer into the beamline environment, allowing simultaneous UV-Vis absorption and Raman spectroscopy.

Limitations

The spectrometer is not yet permanently installed and requires further commissioning for optimal use with protein crystals.
