In photoshop, double click the color picker in the tool bar. When the options box pops up, type in the rgb values or the cmyk values that you have. When the color is showing in the little box, click on "custom" or "library" (can't remember what the option is to pull up the PMS library) and Photoshop automatically pulls up the PMS color that's closest to the one you have selected.
Pantone color
RGB is a device dependent colour space, Pantones are fixed, there isn't a conversion without reference to the icc profile. If you define the RGB, by saying AdobeRGB1998 or sRGB, then the question makes sense.

Surprisingly, that actually made sense. So the use of Pantones, can be classed by the application ie Adobe, Corel and somewhat independent to the the factual samples shown in the Pantone "Wheel" .... correct?

AdobeCorel have a 'working profile' so they know what colour your RGB values represent. They have mixed success. A lot of Pantones are outside the RGB/CMYK colour space. That's why they are used!
