  Dual Comb Spectroscopy proved its versatile capabilities in molecular
fingerprinting in different spectral regions, but not yet in the ultraviolet
(UV). Unlocking this spectral window would expand fingerprinting to the
electronic energy structure of matter.This will access the prime triggers of
photo-chemical reactions with unprecedented spectral resolution. In this
research article, we discuss the milestones marking the way to the first UV
dual comb spectrometer. We present experimental and simulated studies towards
UV dual comb spectroscopy, directly applied to planned absorption measurements
of formaldehyde (centered at 343 nm, 3.6 eV) and argon (80 nm, 16 eV). This
will enable an unparalleled relative resolution of up to $10^{-9}$ - with a
table-top UV source surpassing any synchrotron linked spectrometer by at least
two and any grating-based UV spectrometer by up to six orders of magnitude.
