| Description | We have developed a new instrument for uv photoelectron spectroscopy and time-resolved photoelectron spectroscopy in liquid microjets. We have published our first paper using this instrument and have data for other chromophores that is currently being analysed. |
| Exploitation Route | Our instrument is versatile so can be used for probing the photochemistry of a wide range of materials. |
