[NTR] add Raman Spectroscopy subtypes according to ISO specs

[StroemPhi]

This issue addresses the need to have classes in VIBSO that represent the various Raman spectroscopy assay types defined in the ISO18115:3 specs.

How we will do this is described in the below comment by@Zack-83.

In Raman.methods.ISO.CHMO.CHARISMA.xlsx we edit the proposed definitions, the priority of which terms from our sources to include, what superclasses they have and other information about them. If you want to add a comment or propose a change in it, please download the most current version attached here and add then upload your version in a new comment below.

A visual overview is also offered:

[Zack-83]

Our authoritative sources: CHMO, ISO18115:3 and CHARISMA, contain an overview of Raman sub-techniques (assays).

Neither of these is complete nor strictly coherent. Therefore it is our task to establish a classification of techniques and include it into VIBSO (or propose it to CHMO).

To put order within the jungle, we need to define some positive criteria, e.g.:

• techniques defined by one distinctive adjective (e.g. coherent vs non-coherent)
• techniques defined by an established combination of two or more adjectives (e.g. SERS, CARS)
• techniques which imply a specific set of experimental parameter

as well as some negative criteria:

• techniques defined by a casual combination of two or more adjectives (e.g. deep ultra-violet resonance Raman spectroscopy)
• techniques described in relation to aspects independent from the acquisition method such as sample preparation (e.g. drop coating deposition Raman spectroscopy)

unsure:

• techniques whose denomination does not differentiate it from the default (e.g. laser Raman spectroscopy: nowadays no experiment is conducted without a laser)
• techniques which do not imply different parameters (e.g. infrared vs ultra-violet vs visible)
• techniques which are too seldom, old or restricted (e.g. transmission Raman spectroscoy)

The combination techniques should be included axiomatically, by allowing instances to belong to more classes:

# An example of surface-enhanced anti-Stokes confocal Raman spectroscopy
ex:Measurement1 rdf:type vibso:RamanSpec_SurfaceEnhanced , # implies parameters about the surface
                         vibso:RamanSpec_AntiStokes ,      # implies a restriction on Raman shifts <0
                         vibso:RamanSpec_Confocal .        # implies parameters on the focal depth...

[StroemPhi]

Thanks @Zack-83, I put it on the agenda for tomorrow to be discussed.

[Stefano-Luin]

Please change "emitted" photon with "exiting" photon (or something similar).
Emission usually refers to a single-photon phenomenon in which an excited state decays with emission of a photon.

[Zack-83]

As discussed, we prefer to define the full hierarchy tree starting from "Raman spectroscopy" (an assay) rather than "Raman scattering" (a phenomenon)

Some comments after the call today.

• TERS is related to the setup. The tip which is used as enhancer is connected to a feedback system to control is position and it is indepentent of the sample. SERS can be part of the sample (for example, the molecules to be tested can be synthesized on the surface of nanoparticle or a substrate). However, one can also just drop molecules on top of a SERS substrate (to me, this would be more in the direction of "setup" classification).
• SERS/TERS are types of enhanced spectroscopy but they can also be called near-field (enhanced) spectroscopies or antenna-enhanced spectroscopies.
• I would include wide-field microscopy in contraposition to confocal microscopy.
  Not sure if here is the right place to mention this. So please correct me if I am wrong.
