Chemical shift in NMR spectroscopy is expressed as delta (δ) or tan (t) scale. Choose the correct relationship between δ and t:
- A
δ = 10 – t
- B
δ = 10 + t
- C
t = δ – 10
- D
t = 10 – δ
In NMR spectroscopy, δ (delta) represents the chemical shift, while t is another scale used to express the same concept. The correct relationship between these two scales is δ = 10 – t. This means that to convert from the t scale to the δ scale, you subtract the tan value from 10. The other options are incorrect because they either add instead of subtract, reverse the roles of δ and t, or suggest a subtraction that doesn't reflect the true relationship.
This is the correct relationship between δ (delta) and tan (t) scales in NMR spectroscopy, where δ is calculated by subtracting t from 10.
This option is incorrect. Adding t to 10 does not correctly represent the conversion between the δ and t scales.
This option is incorrect. It wrongly suggests that t is calculated by subtracting 10 from δ, which is not the case.
This option is incorrect. Although it appears similar to the correct relationship, it reverses the roles of δ and t, leading to an incorrect expression.
