Melt-quenched AsxGexSe1-2x glasses over the composition range, 0 xc(2). Raman mode frequency of corner-sharing Ge(Se1/2)4 tetrahedra studied as a function of x, also shows three distinct regimes (or power-laws, p) that coincide with ∆Hnr(x) trends. These regimes are identified with mechanically floppy (x xc(2)) phases. The Raman elasticity power-law in the intermediate phase ,p 1 = 1.04(3), and in the stressed rigid phase, p2= 1.52(5), suggest effective dimensionalities of d = 2 and 3 respectively.
