notessubmitter remarks + registry

Submitter packet included only the specimen and a printed sheet bearing the wavenumber 612 cm⁻¹ and no other text. Raman acquisition reproduces a feature at this wavenumber within ±1.5 cm⁻¹ of the printed value. No prior contact between the registry and the submitter is on file.
