Commentaar:

Luminescence of pectolite was noted in 1903 by Kunz and Baskerville.

In Mt-St-Hilaire, Pectolite could be confused with Makatite. The major distinguishing feature is the fluorescence. While not all makatite fluoresces, when it does it is moderate to strong blueish white or very pale greenish SW (and sometimes LW as well) and pectolite is fluorescing in pink or orange.

Activator en spectrum:

Voornaamste Activator: Mn²⁺

Andere activatoren: Cr³⁺ , Fe³⁺ , Nd³⁺ ,

Pieks in het spectrum (nm):

Mn²⁺ replacing Ca²⁺ : 580 - 590 - 610nm ( Paterson NJ, USA sample, exc. 532nm)

Fe³⁺ : 722nm (Asbestos Canada sample, exc. 532nm)

Nd³⁺ : 867, 877, 881, 890, 918nm (Mt St Hilaire Canada sample, exc. 780nm)

OH : 652nm (Diako, Sandare District, Mali sample, very sharp peak, exc. 532nm) (Gaft)

Spectrum: Michael Gaft, Petah Tikva, Israel. Plot: Institute of Mineralogy, University of Vienna, Austria, with permission of the authors.

Commentaar over activators en spectra:

Activator: probably Mn²⁺ substituting to Ca²⁺ (see Gorobets)
