t1 Increment delay
 

t1 Increment delay

Hello all, iam trying to key in the correct value for nd0 for a custom written pulse program. In doing so i ran into confusion as the pulse sequence adopt constant time approach.

I read from the Bruker maual that for F1(indirect dimension), SW = 1/(in0*nd0), where SW:spectral width, in0: incremental delay for d0 (t1 increment), nd0: number of d0 delays. Based on this formula, i assume that given a SW value, in0 will be calculated by Bruker software for a defined nd0 and vice-versa (SW being calculated from the in0 value). So i can guess the in0 and nd0 for the following cases would be,

A) ||

(in0 = t1(dwell time), nd0 =1)B) ||

(in0 = t1(dwell time)/2, nd0 =2)C) ||

(in0 = t1(dwell time)/4, nd0 =4)My problem is, the experiment is an interleaved one with type (C) experiment performed first followed by type (B) experiment. Since i cannot set two different values for d0 and nd0, iam not sure how to proceed.

Will it be fine if i altogether ignore d0 and use 6 different delays (e.g d20 to d25) with its respective increments (in20 to in25), and do not worry about nd0 value at all? Will it cause any problem while running the experiment?
