Query: Molecular excitations: a new way to detect Dark matter   We believe that the Dark Matter (DM) search should be expanded into the
domain of detectors sensitive to molecular excitations, and so that we should
create detectors which are more sensitive to collisions with very light WIMPs.
In this paper we investigate in detail di-atomic molecules, such as Fused
Silica material with large OH-molecule content, and water molecules. Presently,
we do not have suitable low cost IR detectors to observe single photons,
however some OH-molecular excitations extend to visible and UV wavelengths, and
can be measured by Bialkali photocathodes. There are many other chemical
substances with di-atomic molecules, or more complex oil molecules, which could
be investigated also. This idea invites searches in experiments having large
target volumes of such materials coupled to a large array of single-photon
detectors with Bialkali or infrared-sensitive photocathodes.
