Test: Two-dimensional Nuclear Magnetic Resonance (2D NMR)
20 questions
Question 1: The HSQC experiment is classified as a cross-correlated 2D NMR experiment.
A. Yes
B. No
Explanation: The study materials list HSQC under the category of 'CROSS-CORRELATED' experiments in the 'TYPES OF 2D NMR EXPERIMENTS' section.
Question 2: The ${}^{1}\mathrm{H}-{}^{1}\mathrm{H}$ COSY experiment is categorized as a cross-correlated experiment.
A. Yes
B. No
Explanation: The study materials explicitly list ${}^{1}\mathrm{H}-{}^{1}\mathrm{H}$ COSY under the 'AUTOCORRELATED' experiments category, not 'CROSS-CORRELATED'.
Question 3: In a ONE-PULSE SEQUENCE, magnetization is tipped into the xy plane after a 90-degree pulse.
A. Yes
B. No
Explanation: The study materials state that 'After 90° pulse magnetization is tipped into the xy plane' in the context of the ONE-PULSE SEQUENCE.
Question 4: The HMBC experiment is designed to detect direct carbon-hydrogen correlations.
A. Yes
B. No
Explanation: The study materials provide the full name for HMBC (Heteronuclear Multiple Bond Correlation) and an image, but do not describe what specific types of correlations it detects. Therefore, it cannot be confirmed from the provided text that HMBC detects direct carbon-hydrogen correlations.
Question 5: After a 90-degree pulse, the magnetization remains along the direction of the applied magnetic field.
A. Yes
B. No
Explanation: After a 90-degree pulse, magnetization is tipped into the xy plane, rather than remaining along the direction of the applied magnetic field.
