`ex_ovl4pdeer`¶

4-pulse DEER experiment with overlapping observer pulse

Syntax¶

info = ex_ovl4pdeer(t)
pathways = ex_ovl4pdeer(t,param)

Parameters

t - Time axis (M-array), in microseconds
param - Model parameters (array)

Returns

pathways - Dipolar pathways (array)
info - Model information (struct)

Model¶

This experiment model has two modulated pathways and an unmodulated contribution. The second modulated pathway results in the 2+1 contribution at the end of a 4-pulse DEER trace.The kernel is

$K(t,r) = [\Lambda_0 + \lambda_1 K_0(t-T_0^{(1)},r) + \lambda_2 K_0(t-T_0^{(2)},r)] B(t-T_0^{(1)},\lambda_1) B(t-T_0^{(2)},\lambda_2)$

where $T_0^{(1)}=0$ and $T_0^{(2)}$ are the refocusing times of the two modulated dipolar pathways.
