How many 1h signals does geraniol have
WebSep 28, 2024 · Storage pests pose a great threat to global food security. Here, we found that the essential oil (EO) extracted from E. densa possesses obvious effects against the insects that threaten stored-products. In this work, we investigated the chemical constituents of the essential oil extracted from Elsholtzia densa, and their insecticidal (contact and fumigant) … WebOct 3, 2024 · There are eight carbon atoms total, so the maximum number of signals is eight. However, there is a mirror plane through the center of the molecule. This reduces the number of signals in half because nuclei that are on either side of the mirror plane are magnetically equivalent. There are four signals total.
