13C-direct detection NMR has several advantages compared to proton detection, including a tendency to relax slower and wider chemical shift range. However, the sensitivity of 13C-direct detection is much lower than that of proton detection because of its lower gyromagnetic ratio. In addition, a virtual decoupling procedure is often performed to remove peak splitting in the 13C-direct detection axis, which further reduces the sensitivity to 1/√2. In this study, to enhance the sensitivity of 13C-direct detection experiments, we

ADHD Test - Is it Right For You? Online services fulfill a massive need by providing a quick diagnosis of ADHD (and possibly treatment). They enable people to skip the lengthy and costly process of obtaining an in-person diagnosis. Online evaluations typically use questionnaires and interview questions to examine core symptoms of ADHD. The tests can differ in accuracy, efficiency and price. Making the Choice Between Online and In-Person Testing Online testing is a great way to test your knowledge and accessibility, as people
