Ratios of the elements of the amide I Raman tensors and corresponding order parameters P₂ and P₄ calculated for the N. edulis dragline

	α1/α3	α2/α3	P2	P4
Pajcini et al. (43)	0.274	−0.016	−0.34 ± 0.02	0.21 ± 0.02
Tsuboi et al. (44)	0.200	0.050	−0.32 ± 0.02	0.19 ± 0.02
Cylindrical Raman tensor	0.164	0.164	−0.31 ± 0.02	0.12 ± 0.02

P₂ and P₄ were determined from the experimental amide I intensity ratios R₁ = 0.31 and R₂ = 0.11.
